Question
Consider the situation shown in figure. Water 
is filled in a breaker upto a height of 10 cm. A plane mirror fixed at a height of 5 cm from the surface of water. Distance of image from the mirror after reflection from it of an object O at the bottom of the beaker is
- 15 cm
- 12.5 cm
- 7.5 cm
- 10 cm
The correct answer is: 12.5 cm
From figure it is clear that object appears to be raised by 
Hence distance between mirror and 
So final image will be formed at 12.5 cm behind the plane mirror
