You see a fish in water at an apparent depth of 1.83 m.The actual depth of the fish,if the index of refraction of the water relative to air is 4/3,must be
A)3.81 cm
B)61.0 cm
C)1.37 m
D)1.83 m
E)2.44 m

Question

Quizplus · Accepted Answer

The apparent depth is given by the formula: apparent depth = actual depth / refractive index. Solving for actual depth gives: actual depth = apparent depth * refractive index = 1.83 m * (4/3) = 2.44 m.
