A light ray traveling in air is incident on one face of a right-angle prism with index of refraction n = 1.49, as shown in the figure below, and the ray follows the path shown in the figure. Assuming e = 59.5° and the base of the prism is mirrored, determine the angle o made by the outgoing ray with the normal to the right face of the prism. 4 Your response differs from the correct answer by more than 10%. Double check your calculations.° Incoming ray |Outgoing ray 90° – el Mirror base

A ray of light travels through air until it strikes the interface between the air and another medium. The incident ray makes an angle of 0, = 32.0° with the normal, as shown in the figure below. Upon passage into the second medium, the ray is refracted, emerging from the interface at an angle 0, with respect to the normal. Air Second medium (a) Suppose that the second medium is polystyrene. What is the angle of refraction, 8, (in degrees)? (Enter your answer to at least one decimal place.) (b) Suppose that the second medium is sodium chloride.

A beam of light is incident from air on the surface of a liquid. If the angle of incidence is 36.2° and the angle of refraction is 25.0°, find the critical angle for the liquid when surrounded by air. Step 1 When light goes from one material into another having a higher index of refraction, the light bends toward the normal line as shown in part (a) of the diagram. 02 air liquid (a) (b) We are given that when = 36.2°, the angle of refraction in the liquid is = 25.0°. Thus, from Snell's law, the index of refraction of the liquid is nliquid = nair sin sin e = (1.00) sin sin 25.0° 0 (0.423)
