Oh my, where to start. Any time a wave encounters something of size the same order as the wavelength, diffraction happens. It does not matter if it is an ocean wave at the tip of a breakwater or a light wave hitting a diffraction grating.
Maybe google single slit diffraction
what is diffraction?
When does it occur?
Which waves will defract more when passing through an opening?

ive tried google its all confusing
Here is a diffraction grating
Note that the angle of the first maximum depends on the wavelength of the light, which allows you to separate wavelengths by their angle.

Probably the easiest one to understand though is the DOUBLE slit so I will look for that

ah, here is a U tube for double slit. I bet that helps

Yeah, cool, that is a pretty good U tube
