Unformatted text preview: cannon COUNTRY HOMEWORK Set 13 on man COUNTRY a) Phys 2114 Instructor: Professor Bandy Fall 2011 At What angle 6 should the laser beam in Fig. 1 be aimed at the mirrored ceiling in order to hit the midpoint of the far wall? A diamond 1s underwater A light ray enters one face of the diamond, then travels at an angle of 30° with respect to the normal What was the ray '3 angle of incidence on the diamond? An underwater diver sees the sun 50° above horizontal How high is the sun above the horizon to a fisherman in a boat above the diver? A meter stick lies on the bottom of a JOO-cm- —long tank with its zero mark against the left edge. You look into the tank at a 30° angle, with your line of Sight Just grazing the upper left edge of the tank What mark do you see on the meter stick 1f the tank 13 (3) empty, (b) half full of water and (c) completely full of water? See Fig.2. A fish is 20 m from the shore of a lake A bonfire is burning on the edge of the lake nearest the fish. a. Does the fish need to be shallow (just below the surface) or very deep to see the light from the bonfire? Explain b. What 13 the deepest or shallowest, depending on your answer to part a that the fish can be and still see light from the fire? A narrow beam of white light is incident at 30° on a 10.0—cm thick piece of glass. The rainbow of dispersed colors spans 1.00 mm on the bottom surface of the glass. The index of refraction for deep red light is LSB. What is the index of refraction for deep Violet light? A 2. 0-cm-tall object 13 40 cm in front of a converging lens that has a 20 cm focal length. 3. Use ray tracing to find the position and height of the image. To do this accurately, use a ruler 01 paper with a grid Determine the image distance and image height by making measurements On your diagram. b Calculate the image position and height Compare with your ray-tracing answers in part a. A 1.0-cm—tall object is 60 cm in front of a diverging lens that has a — 30 cm focal length. Complete as question 7. Line ofsight Mirror 3 m all 1&0 cm meter stick 5m Figure 1 . Figure 2 / /fl 1!
