Summary of today's Lecture : 1) Standing waves are formed by overlapping of two waves having same amplitude and frequency and which are travelling in opposite directions. 2) In standing waves, all particles are performing SHM with same phase and different amplitude (which depends on position of particle). 3) In waves all particles have same amplitude and different phase at same point of time while in standing waves, all particles will have same phase at same time but different amplitude. 4) Nodes are those points whose amplitude is zero and are found at a/2 , a, 3a/2 , 2a , 5a/2,....[a means lamda]. Nodes are always at mean position irrespective of time. 5) Antinodes are those particles whose Amplitude is maximum almong all and are found at a/4 , 3a/4 , 5a/4 , 7a/4 , ........ 6) Equation of a standing wave is y = 2A sin(kx) cos(wt) Where 2Asin(kx) is amplitude of wave and phase is defined only by t and that's why at same point of time all particles of standing waves have same phase

at 34:00 superbbb explanationn....ding ding ding ding...haha...i couldnt understand why my teachers cant explain like this...even though i m studying it third tym...from a third teacher...but i can only understand physicswallah"s concept purely..best teacher in the world
I’m in my drop year, I spent 2 years dreading this topic, couldn’t ever attempt one question confidently, just thinking I won’t be able to do it, I won’t be able to understand it on my own. I feel so relieved today that I’ve finally learnt this.

Summary of today's Lecture :
1) Standing waves are formed by overlapping of two waves having same amplitude and frequency and which are travelling in opposite directions.
2) In standing waves, all particles are performing SHM with same phase and different amplitude (which depends on position of particle).
3) In waves all particles have same amplitude and different phase at same point of time while in standing waves, all particles will have same phase at same time but different amplitude.
4) Nodes are those points whose amplitude is zero and are found at
a/2 , a, 3a/2 , 2a , 5a/2,....[a means lamda]. Nodes are always at mean position irrespective of time.
5) Antinodes are those particles whose Amplitude is maximum almong all and are found at a/4 , 3a/4 , 5a/4 , 7a/4 , ........
6) Equation of a standing wave is
y = 2A sin(kx) cos(wt)
Where 2Asin(kx) is amplitude of wave and phase is defined only by t and that's why at same point of time all particles of standing waves have same phase

Sir, your explanation on standing waves is very clear .thank you for such videos
I’m in my drop year, I spent 2 years dreading this topic, couldn’t ever attempt one question confidently, just thinking I won’t be able to do it, I won’t be able to understand it on my own. I feel so relieved today that I’ve finally learnt this.

Very Nice sir you are the best teacher ............
I started this lecture at 9:30pm and ended at 12:10am .wow. mind blowing. Thank you Sir 🙏🙏🙏🙏
at 1:18:00 the formula of stationary wave is wrong because we have cos(-Kx ) so the formula will be -2acosKxsinWt
2acos(-kx) = 2acoskx (simple trigonometry)
You are legend ✨💖
Blessed to have a teacher like u....
wonderful session sir as always..
Thank u so much sir ji....
Let's learn to live in present and enjoy the lecture...
Best lecture ever on Standing wave 😍
