Sir, I've been following you from the first day of my ib physics lesson. I've been watching your videos for the past two years and they've been quite helpful. My adventure will come to a conclusion in November 2022. I continue to revise using your videos. Thank you very much for these two years!!!
00:04 This lecture is about standing wave patterns in physics. 00:47 Standing waves are important in physics. 01:27 Standing waves are produced by the superposition of two traveling waves 02:21 Destructive interference creates standing waves with nodes and anti-nodes. 03:03 A standing wave has the same wavelength and frequency. 03:46 The period and frequency of traveling waves are equal to that of the standing wave. 04:29 A standing wave has a velocity equal to wavelength times frequency. 05:14 Standing waves have a velocity of 1 meter per second
Thank you for good content. Question: you form standing waves by fixing the two ends of the medium, making them not move, right? If the standing wave is the result of adding the two component waves (that are moving through each other), how then are those component waves not stationary at the ends? In the animation, we can see that the component waves are not stationary at the ends (e.g. at 1:16). But I thought the ends are fixed? I hope I am making my question clear. Help? I just want to understand standing waves properly lol.
Is there a reason the constituting travelling waves move in an opposite direction? I can understanding that the traveling waves need to vary in relation to eachother to overlap and form the standing waves, but assuming that travelling waves move only in one time direction (from past to future, which would correspond to the x-axis), the red travelling wave is moving Backwards in time. You could make the red traveling wave move in the same direction as the blue one, but at a higher or lower speed as the blue one. This way they will produce standing waves and abide the same law of propagating forward in time. Or am I missing something here? I was basing my interpretation on the study of sine waves in subtractive and additive synthesis in a music production context. Your example might very well describe two water waves moving towards eachother in space.
@@zetace6326 I know, but that wasn’t my question. It was about the direction waves travel to reach the point where their reflections overlap to create complete interference.
Best visual content ever! Thanks!

So so great to hear they've been helpful, thank you!
I miss topic 9! lots of trouble understanding some of those concepts. your lectures have helped me so much, best explanations ever, thank you a lot!

Really nice video. Not struggling anymore :)
Nice explanation 👌.. and even nice animation 😇
Sending thanks from INDIA 😄
This is so clear! Thank u so muchh
Loved it ❤
Thank you so much!

So good
Thanks 👍
Hello I just wanna ask how will you know the number of standing waves are there?
Do you mean the number of wavelengths in a standing wave? I explain how to find that in this lecture: ua-cam.com/video/hCDRaY6xUi4/v-deo.html

A standing wave forms by a reflection of itself that creates interference
@@zetace6326 I know, but that wasn’t my question. It was about the direction waves travel to reach the point where their reflections overlap to create complete interference.
So is superposition happening when the two waves are "in phase" with each other?
THANK YOU!!!
thank you😊
