An illusionist causes a valuable piece of jewelry apparently to disappear by dropping it in a pool of water directly under the center of a circular platform floating on the surface. Find the minimum diameter of the platform that would prevent the jewelfrom being seen. Assume the water surface is calm, the index of refraction of water is 1.33, and the depth of the water is 2.00 m.
