From my understanding white light is made from all of the visible light's wavelength, and since their wavelength is different they would never be coherent, is there a formula that you could give that would better explain this?

the magic coherent thing isn't related to the problem, the crystal just emits white light this image from the problem might help http://ibb.co/QC2LCym

I thought about using the snell’s law because it involves different refractive index but I have no idea why the wavelength would be affected by the snell’s law. I thought that maybe if I found the frequency I might be able to get the wavelength but, I don’t know which formula I should use. I...
