[maskman]

i am searching for a comment that might say there is a small correction in the video. I didnt found. So im saying it.At 1:24:51 (Coherent and incoherent addition of waves) there is slight mistake in final intensity formula, if I proportional to a^2, there should be Io in the formula not Io^2.

[dakshaasreerama]

Corrections:
At 1:19:10 the wave from S2 reaches faster than wave from S1
At 1:20:34 y2=a cos( wt+ 5 pi)
At 1:24:57 I is proportional to 4Iₒcos²(Φ/2) and not 4Iₒ²cos²(Φ/2)

[soumyabhamajumdar]

Ma'am explained such a hard chapter so easily !! Crystal Clear !!

[NehaG_]

Questions are asked most frequently from young's double slit experiment, and rarely from single slit one! So don't worry about it people✌️👍

[sakee_]

It's physics boards day after tomorrow and your videos are the only thing that's keeping me going !! Love from Tamil Nadu !!

[YogendraRathore-XYZ]

2024-25 Batch Attendance Here 😃👇 All the best to my Scholar friends 😁

[asphaltoverload]

The animator behind all these lectures 🔥🔥🔥

[shivyadav]

Ma'am jo hamere school teacher 2 hafte se samjhate hai or humko aache se smj me bhi nhi aata.. Aap usko 2 hrs me pura crystle cleaar kr dete ho... Thank you ma'am for this amazing one shot videoss!! ❤

[byteforce]

Madam, at 1:25:12 I knot square should be only I knot as I knot square proportional to amplitude's square!!!

[priyankasinghchaudhary]

Mam, please post the one-shot video of electromagnetic waves as well. Only that chapter is left. Please, mam. We are waiting for your videos.
Those who want a video on that chapter, either like this comment or comment the same thing yourself so that it may reach mam.

[marcosgaming]

Light is a ray
Light is a particle
Light is a wave
wah wahhhh wahhhwahh😳🤣
😭😭

[khushi-zilg]

concepts hue crystal clear and mam there is sort of magic in your way of explaining things

[jasirirshad]

In YDSE if we assume S¹P=S²P=D
According to the assumption S¹P + S²P=2D
Why don't we take S²P-S¹P=0😶
Yeh bhed bhav kyu?
