You have a source of white light at the bottom of a pool of water. Describe how you would use total internal reflection to filter blue and violet light from being refracted into the air above the pool. Be quantitative. Assume that this is a strange kind of water and use the indices as given below. Assume the index of refraction for all wavelengths of light in air is the same 1.00 .
