A plate of plastic with parallel faces having a refractive index of 1.50 is resting on the surface of water in a tank. A ray of light coming from above in air makes an angle of incidence 34.0 with the normal to the top surface of the plastic.

A light ray in air (n = 1.00) hits turpentine (n = 1.47) at an angle of 35° to the surface. Determine the angle of refraction.

A light ray in a vacuum is an incident on an equilateral triangular prism. It makes an angle of 13.2 degrees with the normal of the prism's surface. It makes an angle of 12.4 degrees with the normal after entering the prism. What is the angle it makes with the far side's normal after exiting the prism?

Problem 13: A ray of light is incident on an air/water interface. The ray makes an angle of 01 = 22 degrees with respect to the normal of the surface. The index of the air is n = 1 while water is n₂ = 1.33. Part (b) Numerically, what is the angle in degrees? 0₂=1 Part (a) Choose an expression for the angle (relative to the normal to the surface) for the ray in the water, 02.
