A beam of light passes through the air (n = 1.00) and enters a diamond (n - 2.42) at an angle of incidence of 40 degrees . Use Snell's Law to find the angle of refraction in the diamondIf the diamond is placed in a tank of water (n - 1.33) and the beam of light enters the diamond at the same angle of incidence, what would be the new angle of refraction Show all work

With the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 1.90
