Question

A fish seems to be at a depth of 75cm from the surface. What is the actual distance from the

surface? (Refractive index of water is 1.33).​

Answer 1

Answer:

n = Real depth/Apparent depth

Explanation:

Refractive index of water = 1.33

Apparent depth = 75cm

Real depth = n× Apparent depth

Real depth = 75 × 1.33 = 99.75cm

If you want in metre then it's 0.9975m

Answer 2

Therefore the actual depth is 100cm. I hope it will help
