Color and Dispersion question?
A sheet of glass has nred = 1.52 and nviolet = 1.55 (red and violet are subscripted words). A narrow beam of white light is incident on the glass at 30 degrees. What is the angular spread of the light inside the glass?
The answer would be 0.4 degrees. I'm totally lost on this question, much help would be appreciated. Thanks!
The solution you're looking for is Snell's Law, which describes the refraction of light in media.
