A container is filled with fluid 1,and the apparent depth of the fluid is 9.00 cm.The container is next filled with fluid 2,and the apparent depth of this fluid is 6.86 cm.If the index of refraction of the first fluid is 1.37,what is the index of refraction of the second fluid?
A)1.80
B)2.41
C)1.57
D)1.20
E)More information is needed to find the value.

The index of refraction of a fluid is inversely proportional to the apparent depth of the fluid. Therefore, the index of refraction of the second fluid is 9.00 cm / 6.86 cm = 1.31 times the index of refraction of the first fluid. Since the index of refraction of the first fluid is 1.37, the index of refraction of the second fluid is 1.37 * 1.31 = 1.80.
