The index of refraction of a transparent liquid (similar to water but with a different index of refraction) is 1.39. A flashlight held under the transparent liquid shines out of the transparent liquid in a swimming pool. This beam of light exiting the surface of the transparen...

The first answer is 20.93, then when I take that and divide it by 18.5 equals 1.13 but that is incorrect. What am I doing wrong? Then using the same formula (1/9.82)- (1/4.06) comes out -6.92 which doesn't seem right either. please help.
