Question

Light is incident along the normal to face AB of a prism that has a refractive index n and an angle ? = 30°, as shown in (Figure 1). When the prism is in air, the light undergoes total internal reflection. However, when the prism is immersed in water, a faint refracted ray emerges at an angle of 79 ° to the normal of face AC. The index of refraction of water at this temperature is 1.333. Part A Determine n. Express your answer to three significant figures. n = Part B What material was used to make the prism? diamond quartz zircon crown glass Figure Incident ray
