Question

*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). Consider the light bulbs to be point sources and give your answer in decimal format. Include a diagram of the problem in your written work
