Physics - Optics: Single Slit Diffraction (5 of 15) Locations of 2nd & 3rd Max & Min = ?

In this video I will find all the locations of the max and min of the diffraction in general.

Next video in series:

This entire series is great for understanding

[valeriereid]

Excellent lecture. Thank you so very much!

I have one question.
Why can't I just write down like (a/2)(sin theta) = 3 lambda/2 to get the second minimum?
(I know this is wrong answer but why..?😵)

[nayakacourse]

why do we have more fringes as theta increases?

[Orlandolcx]

Question: Does theta increase as you split the beam into more and more parts?

[benarjisai]

sir by the final general formula we cant find central max position why is it so?

you don't understand how long I've been trying to find a source that I can understand!
