Sound Waves Grade 10 Do you need more videos? I have a complete online course with way more content. Click here: purchase.kevinmathandscience.... 🟢Follow me on Instagram: / kevinmathscience
hey Kevin, I wanted to ask, can you please do a video on physics grade 10 (electromagnetic radiation) and thank you for all the videos you do they really help.
In the last question when we used the 4000m.s(speed) and calculated the distance my answer came out as 742,8. Would i get full marks for my answer or its just wrong?
So in the second question i used the v=f×lambda 340=f × 70 so forth. After i got my frequency. I calculated the period and the answer was 0,2 s . Am i wrong ir right for doing that?
in the calculation with the steel railing isnt A's answer 0,295 because the question said how long will it take the sound to reach YOU not how how long will take for the sound to come back and forth same with B isnt the answer 0,25
It's the same distance regardless of the time it takes for the sound to reach the other person,The distance between the 2 steel railings are always the same-The only difference is that it takes 2 secs longer for the sound to he heard through Air.The distance between the 2 steel railings are still the same

In question 2 you can use v=f(lambda) you get frequency of 4,86hz then you use formula of t=1/f you still get 0,21s
Amazing 🎉 the last question👌🏾
Yeah the last question was awesome

i think he has but its on his website
The last question is hard, I really gotta watch it again but anyways Kevin you are the best🎉

7:30 why do we multiply instead of dividing?
heyyy Kevin when will you do "Electromagnetic Radiation " and "Linear Pattern" for grade 10??
No sorry😢 this is my alt btw
So in the second question i used the v=f×lambda
340=f × 70 so forth. After i got my frequency. I calculated the period and the answer was 0,2 s . Am i wrong ir right for doing that?
How do you know whether you should use the D,s,t thingie or yhe one with the lamda and stuff?
you use the d,s,t when they just give you a distance and don't tell you it's the wavelength
Can you please make a video for light waves
Heyy kevin this video was helpful can you please also do electromagnetic radiation for grade 10
Kevin sir please can you make one whereby you talk about 2 cycles of a sound wave
Im sure the mountains aprechiated the conversations 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
You're also writing tomorrow?
Why are we diving by two after getting the actual answer?
in the calculation with the steel railing isnt A's answer 0,295 because the question said how long will it take the sound to reach YOU not how how long will take for the sound to come back and forth
same with B isnt the answer 0,25
Kevin why is the distance between the air and steel the same?
It's the same distance regardless of the time it takes for the sound to reach the other person,The distance between the 2 steel railings are always the same-The only difference is that it takes 2 secs longer for the sound to he heard through Air.The distance between the 2 steel railings are still the same
Wait how do u calculate when the period is 0,002s
In question 4 they asked for time (how long) not distance
hey Kevin, I wanted to ask, can you please do a video on physics grade 10 (electromagnetic radiation) and thank you for all the videos you do they really help.
chaai bro 😭
