A light ray in air is incident on an air-to-glass boundary with an angle of incidence of 45.0° with the normal.  It is refracted in the glass with an angle of refraction of 22.0° with the normal.  What is the index of refraction of the glass?

Light in a vacuum is incident on a transparent glass slab. The angle of incidence is 31.1° . The slab is then immersed in a pool of liquid. When the angle of incidence for the light striking the slab is 24.8°, the angle of refraction for the light entering the slab is the same as when the slab was in a vacuum. What is the index of refraction of the liquid?

A parallel sided plate of glass with an index of refraction of 1.60 is in contact with the surface of water (n=1.33) in a tank. A ray coming from above makes an angle of incidence of 30.0° with the normal to the top surface of the glass plate. (a) What is the speed of light in the glass plate? (b) What is the critical angle between the glass and the water? (c) What angle does this ray make with the normal in the water? (d) Include a diagram of the situation. [Diagram 3 pts.]

A ray of light hits the surface between air and an unknown material at an angle A of 58.8°. It travels through the unknown material at an angle B of 38.5° relative to the vertical. What is the index of refraction of the material?

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?

A light ray in glass (refractive index 1.57) arrives at the glass-water interface at an angle of 0 = 48° with the normal. The index of refraction of water is 1.33. What is the angle of refraction @ that a refracted ray makes with the normal ? water glass O 42° O 56° O 61° O 20°
