A glass sphere of radius 5 xx 10^-2 m has a small bubble 2 xx 10^-2m from its centre. The bubble is viewed along a diameter of the sphere, from the side on which it lies. How far from the sphere will it appear? Refractive index of glass 1.5.

In a spherical glass marble of radius 6 cm, a small air bubble is formed at 1 cm from the centre of the marble. The apparent position of the air bubble from the nearest point on the surface of the marble is about, (refractive index of glass is 1.5.)

A glass sphere (mu=1.5) of radius 20 cm has a small air bubble 4 cm below its centre. The sphere is viewed from outside and along a vertical line through the bubble. The apparent depth of the bubble below the surface of sphere is (in cm)
