A beam of light traveling in air is incident on a trans-parent plastic material at an angle of incidence of 50o. The angle of refraction is 35o. What is the index of refraction of the plastic?
Answer to relevant QuestionsA beam of light enters water from air. (a) Will the angle of refraction be (1) greater than, (2) equal to, or (3) less than the angle of incidence? Explain. (b) If the angle of incidence is 50o, find the angle of ...A beam of light in air is incident on the surface of a slab of fused quartz. Part of the beam is transmitted into the quartz at an angle of refraction of 30o relative to a normal to the surface, and part is reflected. What ...A person looks over the edge of a pool and sees a bottle cap on the bottom directly below, where the depth is 3.2 m. How far below the water surface does the bottle cap appear to be? A beam of light is to undergo total internal reflection through a 45o – 90o – 45o prism (Fig. 22.27). (a) Will this arrangement depend on (1) the index of refraction of the prism, (2) the index of refraction of the ...For total internal reflection to occur inside an optic fiber as shown in Fig. 22.29, the angle u must be greater than the critical angle for the fiber–air interface. At the end of the fiber, the incident light undergoes a ...
