Locate the Object Part A You stand near the edge of a swimming pool and observe through the water an object lying on the bottom of the pool. Which of the following statements correctly describes what you see Hint 1. How to approach the problem When you look at the object, light rays coming from the object travel through the water, cross the water-air interface, and reach your eyes. Because of the difference in index of refraction between water and air, a ray coming from below the water surface changes in direction at the water-air interface. Your eyes, however, can see only the direction of the ray emerging from the water surface, and nothing about that ray tells you that it bent as it crossed the water-air interface. Use the law of refraction to determine how the direction of propagation of the ray crossing the water-air interface changes. Finally, to determine the apparent position of the object, you may find it useful to draw a picture that includes a light ray traveling from the object,
