Thank you for your videos, my teacher is just not eloquent enough to explain even the most simplest thing, at times. Keep up the good work!

Thank you sir for such brilliant videos.

Sir I am really pleased by your explanation. Thank u very much.

Sir,thanks for ur grate videos,they really helped me with my physics!

You can just write it as a ratio of wavelength to radians where *λ:2π* so half the wavelength, you get *π* .

You're honestly a lifesaver sir!! I am writing my (cie) A levels, both AS and A2, this Oct/Nov (6 months earlier than my classmates). Your videos have been immensely helpful for me understand the Physics topics especially since your explanation is in depth. Studying by myself is just so difficult, having someone to explain makes it much easier. So thank you very much for posting these videos!

Summarised a fifty minute lesson in five, I think that's perfect

Can there be antinodes in the bottom side of the string (reflected wave antinodes)? Because you only marked the antinodes that were on top of the string, not the ones at the bottom

organ pipes, doppler effect, and understanding progressive and stationary waves are the most hard topics I till date experienced in physics(I am 13 years old) but the video gave clarity on the concepts

Why does there have to be an antinode at the open end? Can't there be a node aswell sometimes but the standing wave continues because it's open ended?

naheemah akinwale the wave oscillates. That’s showing the peak as it moves up and down. It’s stationary doesn’t mean it stays still.

What actually is natural frequency. You missed resonance part.

At 7:18 by "conditions" is he referring to the phase difference ? ( as in the case should be in phase)

@KennethU

3 жыл бұрын

By conditions he means like external forces, so if something is acting about one wave it has to do it on the other two, the waves there to be the exact same just going in opposite direction

nice

What does superimpose mean

thanks a lot for your video, but I had a question.AT the start of the video, you said that a wave can be thought of a circle, which it stars from a point and ends at the starting point, and a full circle is 2pi radians and half of a circle is like 1 pi radian but for the sine graph , it goes back to its original position at half of the period which is 1 pi in circle graph , so i think for circle graph it should be 2 circles instead of asingle circle.

@musarasheed1443

5 жыл бұрын

while you aren't wrong about the fact it goes to its original displacement after 1 radian, the definition of 1 oscillation is going from the "maximum positive point" or the positive amplitude, then going to the "maximum negative point" or the negative amplitude and returning to the equilibrium position. a particle has to go to these 2 extreme points once for it to be considered 1 amplitude. That is why 1 wavelength looks the way it does (1 positive hump then 1 negative hump).

At 6:00 why do the waves not cancel each other out as a peak is meeting a trough? (Also your videos are so helpful they have hopefully saved my physics a level on Monday!!)

The reflected wave cancels out the first wave and thus creates that point to have an amplitude of 0. In other points the two points will add together and create different amplitudes
