There is a small air bubble at the centre of a solid glass sphere of radius $r$ and refractive index $μ .$ What will be the apparent distance of the bubble from the centre of the sphere, when viewed from outside?

Options:

Answer:

Solution:

' As the object is at centre of the sphere. $∴$ All rays will fall normally on surface, hence they do not deflect. Thus, a virtual image is formed at the centre $O$ . $∴$ Apparent depth $=$ Real depth
