Question

a fish appears to be 1 m below the surface of a pond when viewed almost directly above by a fisherman. what is the actual depth of the fish?

Answer 1

Refractive index = Real depth / apparent depth
Refractive index of water = 1.33
=> 1.33 = x/1
=> x = 1 X 1.33 = 1.33m

Hence the fish is 1.33m deep
