As I understand it, when you beam white light through a glass prism, light disperses and refracts. Red light refracts the least and violet light refracts the most. I am dying to know: why do different frequencies of light have different angles of refraction? Specifically, why is it that an increase in frequency corresponds to an increase in the refractive index?
I was guessing that this is a result of interaction with the medium. As red light has the least relativistic momentum, it would lose the most energy. This would translate into a smaller angle of refraction. Violet light, being much higher in energy, would be affected the least, and therefore would exhibit a greater angle of refraction.
Thoughts?
