A diver with 20/20 vision removes his mask underwater.What can be said about how the diver sees without his mask underwater? The index of refraction of water is 1.3 and the index of refraction for a human lens is 1.4.
A)The underwater objects are clearly seen as the diver retains 20/20 vision.
B)The underwater objects appear blurry as the diver becomes near-sighted (eye lens produces images in front of retina).
C)The underwater objects appear blurry as the diver becomes overly far-sighted (eye lens produces images behind the retina).
D)The underwater objects appear inverted to the diver.

Without the mask, the refractive power of the cornea is reduced due to the similar refractive indices of water and the eye's lens, causing images to form behind the retina, making objects appear blurry.
