is 1.45. 3. A light ray travels from air to glass with an angle of incidence of 50 degrees. The light ray continues to travel through glass material into diamond. At what angle does the light ray make with normal line at it enters the diamond material? 4. A ray of light traveling in air strikes the surface of a polished agate slab (n=1.54) on display in your friend's home. If the ray in the agate makes an anlge of 29 with S1.3 2.42
