A ray of light is incident on a flat surface of a block of cubic zirconia, with an index of refraction of 2.2, that is submerged in wate The ray is split at the surface, where the angle of refraction of the transmitted ray is 11.9°. What is the angle of reflection (in degrees) of the reflected ray?

A ray of white light traveling through air enters a block of glass that has an index of refraction of 1.44 for the red end of the spectrum and 1.46 for the violet end. If the ray has an angle of incidence of 60.0 degrees with respect to the normal of the interface boundary, what's the angular separation between the red and violet ends of the spectrum within the glass?

A ray of light crosses the boundary between some substance with n = 1.54 and air, going from the substance into air. If the angle of incidence is 29◦ what is the angle of refraction?   Calculate to 1decimal.

Total internal reflection: The speed of light in a material is 0.39c. What is the critical angle of a light ray in degrees at the interface between the material and a vacuum? (keep 2 sig figs please)
