Fig shows a small air bubble inside a glass sphere `(mu = 1.5)` of radius 10 cm. the bubble is 4.0 cm below the surface and is viewed normally from the outside. Find the apparent depth of the bubble.

2cm

3cm

4cm

5cm

Text Solution

Verified by Experts

The correct Answer is:

`(n_(2))/V-(n_(1))/U=(n_(2)-n_(1))/R` so `1/V-1.5/(-4)=(1-1.5)/(-10)`
so `v=-40/13~~-3cm`
