A truck driver whose eyes are 2.00 m above the road, where n = 1.0003, looks forward. She has the illusion of seeing a patch of water ahead on the road, where her line of sight makes an angle of 1.20 below the horizontal. Find the index of refraction of the air just above the road surface. ( Hint: Treat this as a problem involving total internal reection.) 5. A concave spherical mirror has a radius of curvature of 20.0 cm. Locate the images for object distances of (a) 40.0 cm, (b) 20.0 cm, and (c) 10.0 cm. In each case, state whether the image is real or virtual, and upright or inverted, and nd the magnication. 6. Problem 23.33, Page 820. 7. Problem 25.25, Page 881. 8. Problem 25.44, Page 883. 9.
