A fish inside a pond appears to be at a depth of 1.5m when viewed vertically from above. The refractive index of the water in the pound is 1.3. Calculate the apparent displacement of the fish?

A. 2.50m
B. 1.95m
C. 1.50m
D. 0.45m

Correct Answer: Option D

D. 0.45m

Explanation

Real depth = n x apparent depth

= 1.3 x 1.5 = 1.95m

Apparent displacement = 1.95 – 1.5 = 0.45m
