Lightning is the spark that can be seen in the sky during rains and thunder is the loud sound heard just after lightning.though they occur at the same time lightning is seen before thunder is heard ,this is because the speed of light is much more than the speed of sound.The speed of light in air or vaccum is approximately 3*10⁸m/s and the speed of sound in air is 343m/s.Thus,the light from lightning travels to us much faster than the sound produced by it.
Sir and their team should be appreciated as they are providing free and simple knowledge to everyone. I had applied for [NSO] and these videos are helping me a lot two clearing my concepts.
The speed of light is more than sound due to more speed of light it reaches us before sound therefore lightning is seen earlier and sound is heard later
Ans - the light trevels at the speed of 300000km/sec. Which is very large in comparison to the speed of sound which trevels all then 3.30 m/sec. In air :that is why lightning is soon at the rate earlier and thunder is heard later 😊😊
Our teacher gave us an example of noise : (Students understood 😅) Sir she said the class the students perfect example of N-O-I-S-E . Then I understood okkk that's why whe always remember the name of all the naughty students first 🥇 She says (❤when you all will go to ninth you will forget us but I've seen whenever old students come to meet there teachers very old teachers mostly remember naughty students 😊❤) but teacher even sir they all love us equally 🤩 SIR I HAVE EXAM ON MONDAY AND WHEN MY RESULTS WILL COME SURELY I WILL TELL SIR 😊 thank you
😊because light travels faster than the sound travels that is why we first see lightening and then after some second we hear thunder in the sky during rain .❤❤
H.w questions This is because the speed of sound is lesser than than the speed of light so as the speed of light is more it travels faster then the sound is light is seen earlier and sound of thunder is heard later Thankyou for such a wonderful class and for your precious time where you shared us some knowledge ❤❤❤
Lightning and thunder occur at the same time and distance from us. However, lightning is seen before thunder is heard because light travels faster than sound. Light travels at a speed of about 300,000,000 meters per second, while sound travels at 340 meters per second.
During a thunderstorm, lightning is seen first and thunder is heard later on because light travels faster than sound. Lightning always comes with thunder. If you see a lightning flash but cannot hear anythunder, the thunderstorm is most likely be quite far away from you.
lighting is seen earlier because speed of light is 3*10^8 m/s whereas the speed of sound is 340 m/s .Therefore we see thunder initially and hear sound later
The reason for the delay in hearing the thunder, is due to the difference in the speed of light and sound. Light propagates millions times faster than sound.
The speed of light is 300000km/s and the speed of sound is 330m/s . Light travels faster than sound.....Hence lighting is seen earlier and sound that's the thunder is heard later
Homework:- The speed of light is fast....so lightning comes way before the thunder. The sound propagating through medium air is much slower ...so it will come way after the lightning
The speed of sound (344 ms) is far less than the speed of light 3×108 ms in air. Thus sound of thunder will take more time to reach the observer compared to light. Hence, a flash of light is seen before we hear thunder. Therefore, lightning is seen earlier and thunder is heard later. Answer of home work question
Lighting and thunder take place in the sky at the same time and at same distance from us. Lighting is seen earlier and thunder is herad later as speed of light is more than sound.
Lightning and thunder take place in the sky at the same time and at the same distance from us but Light travels faster than sound. thank you, sir, now I understand this chapter better than before. :)
The lightning and thunder are seen when there is a heavy rain and lightning is seen before than thunder because you generally seen that if lightning 🌩️⚡ falls on somebody or something it will burn it and it is because of the high speed of lightning so lightning is seen earlier because speed of lightning is very much higher than the speed of thunder, thunder speed is 330m/s and which is very less because speed of lightning is seen and calculated as 3 × 10 to the power 8 hence, lightning is seen earlier than thunder
Homework answer sa we see to the lightning first and thunder after because the speed of light is more than the speed of sound in air sahi speed of sound =3×100000000 metre per second and speed of sound = 150 metre per second hence prooved😁
18:44 the speed of light is more than the speed of sound thus, lightning is seen first, which is accompanied by thunder later
All the best for your tomorrow exam
Mine is today
Thanku

actually sound cannot travel in vacuum so you can correct you comment
Google 😊 19:39
Seedha answer
Light travels faster than sound
she said that "the speed of sound in air is 343m\s....."@@fusiongaming132
You are wrong the answer is right
Sir and their team should be appreciated as they are providing free and simple knowledge to everyone. I had applied for [NSO] and these videos are helping me a lot two clearing my concepts.
Same bro😅 Byju's videos help a lot🫶🏻
18:56 It is because the speed of light is faster than that of sound 😊
The speed of light is more than sound due to more speed of light it reaches us before sound therefore lightning is seen earlier and sound is heard later
Tysm I have exam tomorrow 😂😂
13:58-Threshold of pain=130db
14: 44 your voice is like mic mouse 🐭
😅😅😅😂😂😂right😅
FR
Can I get ur socials ?
Homework Answer:- The Speed of the sound is much smaller than the speed of the light.
Thus we see thunder first and then listen to the voice of it.
19:05 because speed of light is faster than sound
Homework question ❓
Cause light travels Faster than sound
Ans - the light trevels at the speed of 300000km/sec. Which is very large in comparison to the speed of sound which trevels all then 3.30 m/sec. In air
:that is why lightning is soon at the rate earlier and thunder is heard later 😊😊
Sound travels at 330 m/s not 3.30 m/s
Our teacher gave us an example of noise :
(Students understood 😅)
Sir she said the class the students perfect example of N-O-I-S-E .
Then I understood okkk that's why whe always remember the name of all the naughty students first 🥇
She says (❤when you all will go to ninth you will forget us but I've seen whenever old students come to meet there teachers very old teachers mostly remember naughty students 😊❤) but teacher even sir they all love us equally 🤩
SIR I HAVE EXAM ON MONDAY AND WHEN MY RESULTS WILL COME SURELY I WILL TELL SIR 😊 thank you
Bro r u a human?
Or created this for an AI?
HW question:- bcz speed of light is faster than Speed of sounds 👍🏻😊
sir mejhe app ki wajha se paad aa gaya
bichara mai
Wtf? 😂😂
It's because of time traveling of sound wave😊
Like karo agar tum exam se pehle aaye ho
Thanks sir
Tomorrow is my exam 😝😝
This video helped me to quickly revise
Lightning is see to be earlier during the thunderstroms this is because the lightning travels with more speed than sound produced in a thunderstorm
19:01 It's simple
The speed of light is fast as the speed of sound
😊because light travels faster than the sound travels that is why we first see lightening and then after some second we hear thunder in the sky during rain .❤❤
Because lightning have frequency than thunder strom etc
False
H.w questions
This is because the speed of sound is lesser than than the speed of light so as the speed of light is more it travels faster then the sound is light is seen earlier and sound of thunder is heard later
Thankyou for such a wonderful class and for your precious time where you shared us some knowledge ❤❤❤
Legend watch this video 15 hrs before exam .
Lightining takes place first because the light travells faster thand sound
Lightning and thunder takes place in the sky at the same time and at the same distance from us but light travels faster than sound.
19:04 light travels fast than sound
18:41 Because speed of light is faster than speed of sound 👍
Lightning and thunder occur at the same time and distance from us. However, lightning is seen before thunder is heard because light travels faster than sound. Light travels at a speed of about 300,000,000 meters per second, while sound travels at 340 meters per second.
14:51 That was unexpected!!🤣
Legend are watching 1 day before exam and in 2x speed 💀
Us bro us ❤❤
Because speed of light is greater than speed of sound
well explained sir please upload a rapid rivision of crop production and manegment class 8 .....
😢😢😢😢😮😮😮😅😅😅😅😅😅😂😂😂😂😂😂😊
Speed of light (3*10^8 m/s) is much faster than the speed of sound (343m/s) is why we see the lightning before the thunder
05:11 😂
During a thunderstorm, lightning is seen first and thunder is heard later on because light travels faster than sound. Lightning always comes with thunder. If you see a lightning flash but cannot hear anythunder, the thunderstorm is most likely be quite far away from you.
Thank you sir
There was little confusion occuring in mind but noew it is clear....very thanks
lighting is seen earlier because speed of light is 3*10^8 m/s whereas the speed of sound is 340 m/s .Therefore we see thunder initially and hear sound later
answer= We har sound after the thunder bcoz light travels faster than sound
Thank u sir for this wonderful session .
Because speed of light is more than speed of sound and lightning ⚡ occur in air and sound is lesser in air and more in solids
The reason for the delay in hearing the thunder, is due to the difference in the speed of light and sound. Light propagates millions times faster than sound.
19:56
14:44 🤣🤣😂
Speed of light which is 3×10⁸ m/s, is more than speed of sound which is (nearly) 340 m/s. That's why lightning is seen first.
The speed of light is 300000km/s and the speed of sound is 330m/s . Light travels faster than sound.....Hence lighting is seen earlier and sound that's the thunder is heard later
Speed of light is more than sound and light passes through the cloud easily compared to sound
Homework:-
The speed of light is fast....so lightning comes way before the thunder.
The sound propagating through medium air is much slower ...so it will come way after the lightning
Like please 😅 if you don't like then anty ka beta bunty
the speed of lightning is faster than that of thunder as light travels faster than sound.
1:12
The speed of sound (344 ms) is far less than the speed of light 3×108 ms in air.
Thus sound of thunder will take more time to reach the observer compared to light.
Hence, a flash of light is seen before we hear thunder.
Therefore, lightning is seen earlier and thunder is heard later.
Answer of home work question
Like like karo Agar answer helpful ho to
tak tak tak aha 5:10
Yes
Ans :- 1 upon F so, frequency is 100 therefore 1 upon 100 equal to 0.1s
Lighting and thunder take place in the sky at the same time and at same distance from us. Lighting is seen earlier and thunder is herad later as speed of light is more than sound.
Lightning and thunder take place in the sky at the same time and at the same distance from us but Light travels faster than sound.
thank you, sir, now I understand this chapter better than before. :)
Sound effects were wonderful sir.
Hw
Question
Lightning is heard before the thunder. As light travels faster than sound.
The seed of light is faster than the speed of sound hence we see lighting first .
Sorry speed not seed
speed of light is greater than the speed of sound that is why during thunderstorm lighting is seen earlier and thunder is heard later
Because the speed of light is more than sound. Therefore, we see the lighting earlier and hear the sound later on 🤔
Ans:- because sound travels slower than light
Thank you sir.... in class I didn't understand this chapter that's why I'm seeing this video Thanku so much sir❤😊sirr aap live lelloo
Ans. The speed of light is greater than speed of sound.
We hear lightning first because the speed of light is more than the speed of sound hence, thunder is heard later.
Light travels faster than sound 😊
The lightning and thunder are seen when there is a heavy rain and lightning is seen before than thunder because you generally seen that if lightning 🌩️⚡ falls on somebody or something it will burn it and it is because of the high speed of lightning so lightning is seen earlier because speed of lightning is very much higher than the speed of thunder, thunder speed is 330m/s and which is very less because speed of lightning is seen and calculated as 3 × 10 to the power 8 hence, lightning is seen earlier than thunder
Speed of light 3into m/s
Speed of sound 340 m/s
Speed of light is greater than speed of sound
phonk lover attendennce here
This session was helpful
Because light is fastest in whole universe and that why we see lighting earlier then thunder ⛈️
Will we having these kind of videos for ch 11 , 12 and 13 class 8?
Homework answer sa we see to the lightning first and thunder after because the speed of light is more than the speed of sound in air sahi speed of sound =3×100000000 metre per second and speed of sound = 150 metre per second hence prooved😁
Lightning is seen eariler than we hear the sound of thunder because speed of light (300,000,000 m/s) is more than the speed of sound (330 m/s)
answer: because the speed of light is more than that of sound
14:45 bro be came mario😅
Because light is speeder than sound so lightning is seen earlier and it is sound later
brother my exam is at 9:00 am and the time is 8:00am
Because light can travel faster than sound and another reason is sound is travel slow in air
Home work questions
Because speed of light is more than speed of sound
Funny line 5:10😂😂😂
Yooooooo❤
Got 97 percentage in the exam because of you 🥰
Have to watch it as a 9th grader dueeeee toooo olympiadsss 😂😅
Because light is faster than the sound so first we can see the light and then hear the thunder
Speed of light is more faster than sound that's why wee see lightning first and listen song later
thank u sir
Sir the homework answer is speed of light is much faster than the speed of sound by which we hear thunder later
Ans = The sound has less speed than light
Answer: because the speed of sound in air is 340m/s and speed of light is 3*10⁸m/s. That's why thunder is heard after the flash of light 🙏
Because light is fast and thunder is slow
In short I think the light travel more faster than sound and that's the reason.....
Because light travels faster than the sound
SPEED OF SOUND IN AIR IS 346 M PER SEC
THATS WHY WE CAN HEAR SOUND LATE
Legends watching few hours before exam ☠️💀💀
As light travels faster than sound
18:00 😂😂
