A large hall in a museum has a niche in one wall. On the floor plan, the niche appears as a semicircular indentation of radius 2.50 m. A tourist stands on the centerline of the niche, 2.00 m out from its deepest point, and whispers “Hello.” Where is the sound concentrated after reflection from the niche?

5) a) An underwater diver sees the sun 50oabove horizontal. How high is the sun above the horizon to afisherman in a boat above the diver? b) A 4.0-m-wide swimming pool is filled to the top. The bottom of the pool becomes completely shaded inthe afternoon when the sun is 20oabove the horizon. How deep is the pool? c) A light ray travels inside a horizontal plate of glass (n= 1.52), striking its upper surface at an angle ofincidence of 60o. This ray is totally internally reflected at the glass-air boundary. A liquid is then pouredon the top of the glass. What is the largest index of refraction that the liquid could have such that the rayis still totally internally reflected?

In the figure, light is incident at angle θ1 = 41˚ on a boundary between two transparent materials. Some of the light travels down through the next three layers of transparent materials, while some of it reflects upward and then escapes into the air. If n1 = 1.28, n2 = 1.36, n3 = 1.34 and n4 = 1.45, what is the value of (a) θ5 and (b) θ4?
