A ray of light strikes the midpoint of one face of an equiangular (60°–60°–60°) glass prism (n = 1.5) at an angle of incidence of 40.8°. (a) Trace the path of the light ray through the glass, and find the angles of incidence and refraction at each surface.First surface: θincidence =  ° θrefraction =  ° Second surface: θincidence =  ° θrefraction =  ° (b) If a small fraction of light is also reflected at each surface, find the angles of reflection at the surfaces. θreflection =  ° (first surface) θreflection =  ° (second surface)

A ray of light is incident on a flat surface of a block of cubic zirconia, with an index of refraction of 2.2, that is submerged in water. The ray is split at the surface, where the angle of refraction of the transmitted ray is 13.1°. What is the angle of reflection (in degrees) of the reflected ray?

A light ray travelling in medium a is refracted into medium b. The angle of incidence is 50.5° and the angle or refraction is 60.8°. Both angles are measured from the normal to the interface. What is the ratio of the index of refraction of medium a to that of medium b?

A light beam reflects off two parallel reflecting surfaces that are = 202 cm long and separated by a distance of s = 65.0 cm. If the beam of light enters this region as shown, with the angle 0 = 25.1°, determine the following. Ꮎ (a) the number of times the light beam reflects off the left surface Have you redrawn the figure with all angles and distances labeled? How is the entrance angle related to the angle of Incidence and the angle of reflection for the mirrors? times (b) the number of times the light beam reflects off the right surface times
