Just wondering, why is it that blue light will refract less than red light, i.e. why does the fact that blue light has a shorter wavelength mean that it will refract less at a boundary?
I read somewhere that the wavelength decreases of light as it enters an optically denser material, which seems logical given that frequency remains constant and c = f λ. Is there some sort of constant which would mean that if the wavelength of a type of light in material one is x% shorter than that of, say, red light, the wavelength after refraction would be kx% shorter?
I know this is a terribly worded question, this is all new to me and it's a bit difficult for me to put down my thought process.
Thanks in advance!
