Question

the length of a vertical pole at the surface of a lake of water
(mu=4/3) is 24cm then to an underwater fish just below the water
surface the tip of the pole appears to be

Simran · Answer

Actual height =24cm Apparent height =? Apparent height >actual
height and, u=4/3 u= apparent height /actual height Therefore
4/3=apparent height/24 Apparent height =32cm
