Single Slit Interference | Physics with Professor Matt Anderson | M28-19

Let's look at a specific example of single slit interference. In this case, we have a known slit size, and when we shine light through it, we get a diffraction pattern. If we measure the angle from the central maximum to the first minimum, can we calculate the wavelength of light based on this. How do we do it?

amazing video!!! i tried khan academy but your explanation was the only one that discussed the contradiction between the formulas for double vs single slits. thank u!!

Sir if you don’t mind can you pls share the formula sheet which u have mentioned at 3:30

Won't let me past it here, but look at this:

So which corner of the slit did the particle interact with?

[@yoprofmatt]

Great question. Answer: both.

Seeing as the Physics Community has yet to arrive at a consensus on interpreting exactly what Quantum Mechanics really means, we can't say anything about what is actually happening when and if the Wave Function collapses or indeed whether Quantum Mechanics is merely an accurate tool but nevertheless fundamentally incorrect.

Well done Professor 👌 I have it

[@yoprofmatt]

Great 👍

[@fizixx]

Great question to ask! Again....not intuitive --- the same equation for two different scenarios. yeah baby!
