A narrow light beam in vacuum contains light of two wavelengths, 480 nm and 700 nm. It strikes a flat piece of glass at an angle of incidence of 60.000°. The index of refraction of the glass is 1.4830 at 480 nm and 1.4760 at 700 nm
Determine the angle between the two wavelengths as the light travels in the glass.
Instead of calling a white dwarf a "star," you could call it a compact object because it:
