You stand at the edge of a pool and look at a quarter on the bottom of the pool. Is the quarter's actual position closer than it looks or exactly where it appears? Explain your answer.
Homework Answers
The position looks closer than it actually is.
The refraction of light at the surface of water makes pool appear shallower than it really is. A 1m deep pool would only appear to be 0.75 m deep when viewed from directly above.

You are standing on the edge of a swimming pool and looking directly across at the opposite side. You notice that the bottom edge of the opposite side of the pool appears to be at an angle of 26.0° below the horizontal. However, when you sit on the pool edge, the bottom edge of the opposite side of the pool appears to be at an angle of only 13.2°below the horizontal. Use these observations to determine the width and depth...

You are reaching into a pool of water to grab a quarter at the bottom. If the pool is actually 75.0cm deep, how deep does it appear to be? The surface of the pool is flat and calm, and the index of refraction of the water is 1.33.

November 6, 2019 3. As it turns out, a pool of water will also produce an image of a submerged object. Thus, we talk about "apparent depth" of an object. You stand at the edge of a pool with your eyes 2m about the level of the water. You see a stick that you know is 3m long at the bottom of the pool. It appears to you that the stick is 1m below the surface of the water. You...

a) If you dive to the bottom of a deep pool, your eardrums may get uncomfortable or even start to hurt. On the other hand, if you take an airplane flight, you may find your eardrums getting uncomfortable in a different way. Both experiences arise from pressure changes, but how do they differ? Explain in your own words. b) Calculate the change in pressure your eardrums undergo when you dive to the bottom of a 4.85-m- deep swimming pool filled...
