A light ray travels from air, through a tw = 2.00 mm thick layer of water, through a tg 5.00 mm thick layer of glass, and then back into air. The speed of light in air is 3.00 x 108 m/s, the speed of light in water is 2.25 x 108 m/s, and the speed of light in glass is 2.00 x 108 m/s. When the light re-emerges into the air, how much has it moved horizontally, i.e., what is d in Figure 3? The angle of incidence for the light at the air/water interface is 30.0°. = [10 I tw tg

The speed of light in a vacuum is 3.00 ´ 108 m/s. If the refractive index of a diamond is 2.42, what speed does light travel as it passes through a diamond?
