A container is filled with fluid 1 and the apparent depth of the fluid is 5 cm. The container is next filled with fluid 2, and the apparent depth of this fluid is 4 cm. What is the ratio of the indices of refraction of these fluids? n1/n2 =1 O n1/n2 = 4/5 O n1/n2 = 5/4 O More information is needed to find the ratio.
