*D. When a source of light is underwater, the light appears as bright circles formed by light rays refracted from the surface. The picture shows lights at the bottom of a swimming pool and the bright circles on the surface. If the diameter of the light circles on the pool surface is 1.089 m, what is the depth of the pool in meters? For the refractive index of the water in the pool use 1.390 (it is a saltwater pool)....

1 A horizontal cylindrical tank 2.20 m in diameter is half full of water. The space above the water is filled with a pressurized gas of unknown refractive index. A small laser can move along the curved bottom of the water and aims a light beam toward the center of the water sur- face (Fig1). You observe that when the laser has moved a distance S = 1.09m or more (rneasured along the curved surface) from the low- est point...

An LED mounted in the wall of a pool sits 1.6 m below the surface and emits light rays in all directions. Some rays move forward and upward towards the water/air interface. Approximate the LED as a small source. For the following, explain your reasoning with a diagram. a. What is the critical angle in degrees for total internal reflection of the rays at the water/air interface? Should be ~48. b. For light rays that escape the pool, what is...

In searching the bottom of a pool at night, a security guard shines a narrow beam of light from his flashlight, above the water's surface, onto the waiter at a point 2.5 m from his foot at the edge of the pool. Where does the light hit the bottom of the pool measured from the wall beneath his foot if the pool is 2.1 m deep. A triangular prism made of crown glass, n = 1.52, with base angles of...
