A certain kind of glass with index of refraction of 1.65 for blue light of wavelength 430nm and index of refraction 1.615 for red light with wavelength 680nm. If a beam of light containing these two colors has incident angle of 30 degrees what is the angle inside the glass?

Look up Snells law. Remember the two colors will have different angles in the glass, as the refractive index will bend them differently.
