Question

A smallfish, 4m below the surface of a lake if refractive index of water is 1.33 the true depth of fish is

Answer 1

Answer:

5.32

Explanation:

total depth of fish is 5.32

Answer 2

Answer:

5.32m

Explanation:

refractive index = actual depth/apparent depth

1.33=actual depth/4m

actual depth =4×1.33

actual depth= 5.32m
