Question

Water tank appears to be 4m deep when viewed from the top. if refractive index of water is 4 /3 find the actual depth of the tank

Answer 1

Given:

Apparent depth= 4 m

Refractive Index of water=4/3

Answer along with Explanation:

Refractive Index= Actual depth/Apparent depth

4/3=Actual depth/4 m

4/3x4=Actual depth

16/3=Actual depth

5.33=Actual depth
