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.
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 🤩 basically I got 75/80 SIR I HAVE EXAM ON MONDAY AND WHEN MY RESULTS WILL COME SURELY I WILL TELL SIR 😊 thank you
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
Lightning is seen earlier because light travels faster than sound. The speed of the light is appox. 3x10 whole to the power 8 m/sec whereas speed of sound is 340m/s. As a result the sound of thunder takes more time to reach our ears and lightning could be seen earlier.
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 😊😊
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 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. :)
Thanku sir but aap jo english bolta ho na mujha toh samaj aa gayi but sir jin bacho ka liya aap ya video dalta ho na vo toh english samaj hi nii pata hoga Sir
😊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 .❤❤
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.
Lighting and thundering take place in the sky at the same time and at the same distance from us. Lighting is seen earlier and thunder is heard later because speed of light is greater than the speed of sound and therefore, light travels faster than thunder.
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.
Distract mat karo bhai , kya attendence here kya , kuchh bhi bol raha hai kya paa liya attract kar ke mein bhi phonk lover huun but is tarah distraction create karna sahi nahi hai
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
bcoz lighting has light energy, and thundering has sound energy, and as we all know light travels faster than sound....this is why lighting is seen earlier and thundering is heard later...
Sir iam cbse our exams are coming on April 1 can you conduct any tests, quiz , or mind maps? Because I saw your video in light and also in many lessons too but that light lesson had good mind maps.
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.
All the best for your tomorrow exam
Mine is today
Thanku
Same 😭🫵🏻
Thanks but I am the topper of class so I have no risk
Tq
18:44 the speed of light is more than the speed of sound thus, lightning is seen first, which is accompanied by thunder later

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 😂😂
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.
Bro said under 30 min but finished under 20 min
Yeah!!!!!!!! Chalo... I'm not the only one who noticed it😂😂
14: 44 your voice is like mic mouse 🐭

Can I get ur socials ?
The speed of light is more than thunder ,therefore the light is seen first and thunder heard later.

Homework question answer:
Bcz our eyes are infront and our ears are a little back r😅😂
Just kidding real answer is light travels faster than sound..
Any one in kerala 😅

: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
It's because of time traveling of sound wave😊
well explained sir please upload a rapid rivision of crop production and manegment class 8 .....
😢😢😢😢😮😮😮😅😅😅😅😅😅😂😂😂😂😂😂😊
Thanks sir for understanding this chapter you are the teacher 🎉
19:05 because speed of light is faster than sound
Will we having these kind of videos for ch 11 , 12 and 13 class 8?
Ah... I can hear u 5:11
14:44 🤣🤣😂
HW question:- bcz speed of light is faster than Speed of sounds 👍🏻😊
sir is doing pushpa sign at thismoment
Legend are watching 1 day before exam and in 2x speed 💀
Us bro us ❤❤
Thank u sir for this wonderful session .
Homework question ❓
Cause light travels Faster than sound
Light travels faster than sound lol i typed this without looking
it is because the light travels faster than that of the speed of sound thats why lighting is seen first than the sound no matter what the distance is
15:27 that's not infrasound or ultrasound, that's infrasonic sound and ultrasonic sound.
Yooooooo❤
Sir we have that sound travel fast in soild
05:11 😂
Because lightning have frequency than thunder strom etc
False
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
Goated teacher the only one i found who teaches in english and does it better than many others in less time
19:01 It's simple
The speed of light is fast as the speed of sound
Lightning is see to be earlier during the thunderstroms this is because the lightning travels with more speed than sound produced in a thunderstorm
Who is here one day before the exam
5:10 sar uspe ya kispe hu hu bio wali mam ke saath experience
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.
Thanks sir
Tomorrow is my exam 😝😝
This video helped me to quickly revise
Legend watch this video 15 hrs before exam .
19:04 light travels fast than sound

18:56 It is because the speed of light is faster than that 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 .❤❤
Thankyou sirrr😊❤
Because the speed of light is more than the speed of sond 😊❤
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.
Homework question: The speed of light is more than the speed of sound that is why we were able to here the lighting first and the thunder later.
the 3 set of bones are hammer,anvil and stirrup
all the best for your exam tmrw
3:00 best timing
Because the speed of lightning is faster then the speed of sound

Funny line 5:10😂😂😂
6:55
Sir what is pich
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
bcoz lighting has light energy, and thundering has sound energy, and as we all know light travels faster than sound....this is why lighting is seen earlier and thundering is heard later...
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
Light speed is faster than speed of sound, thus we see lighting first and hear sound later
Very nice explanation
Speed of light is faster
i.e. 400000000 for light,340 for
sound 18:44
Because speed of light is greater than speed of sound
Thank you sir
There was little confusion occuring in mind but noew it is clear....very thanks
Sound effects were wonderful sir.
It is important to watch this RUclips video for animals one night before the exam. As if tomorrow is my exam, I am watching today...
