A glass sphere of radius 15 cm has a small bubble 6 cm from its centre. The bubble is viewed along a diameter of the sphere from the side on which it lies. How for from the surface will it appear to be if the refractive index of glass is 1.5 ?

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