Based on the concept of the wave-like nature of light, Huygens' theory of light postulates that the more light was "bent" by a substance the slower it would move while traversing across that substance. A) deflection B) interference C) refraction D) resonance

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
