Young's Double Slit Experiment: measuring wavelength | A Level Physics

This is the best method to carry out Young's double slit experiment in a class room, using simple equipment and a safe laser.

Yoooo man thank you much for explaining the calculations too. I wish my college had thought us practically like this way maybe I wouldn't have developed immense fear of physics that way *sigh*

Good video thanks. I was wondering, is it possible to avoid the single slit diffraction completely and get only the double slit interference pattern. If so, what are the cares that one should take to achieve it..?

How would other colours of light (e.g. purple) with shorter wavelengths fare? Would this method still work?

does this measure amplitude? and if it does, thank you so much, im doing superpositions for my science fair project

Why did you use single slit instead of double slit?
