Question
A transparent glass sphere of radius 
and refractive index μ=1.5 has its one half silvered so that it acts like a concave mirror. Find the position of final image for an object ' O^' at (A) 30 and (B) 20 cm to the left of the front surface of the ball.
- 30 cm to the right of
; at the pole of mirrored surface
- 30 cm to the left of ; at the center of sphere
- 20.9 cm to the right of ; at the pole .
- 20.9 cm to the right of ; at the pole of mirrored surface
; at the pole of mirrored surface
; at the center of sphere
; at the pole .
; at the pole of mirrored surface
The correct answer is: 20.9 cm to the right of ; at the pole of mirrored surface

A hollow sphere of glass as shown in figure has refractive index and has a small mark on its interior surface which is observed from a point outside the sphere on the side opposite to the center. The inner cavity is concentric with the external surface and thickness of glass is everywhere equal to the radius of the inner surface. What is the apparent shift in the position of mark?
