Fig shows a small air bubble inside a glass sphere (mu = 1.5) of radius 10 cm. the bubble is 4.0 cm below the surface and is viewed normally from the outside. Find the apparent depth of the bubble.

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

An air bubble inside a glass slab (µ=1.5) appears 6 cm when viewed from one side and 4 cm when viewed from the opposite side. The thickness of the slab is

A small air bubble in a glass sphere of radius 2 cm appears to be 1 cm from the surface when looked at, along a diameter. If the refractive index of glass is 1.5 , find the true position of the air bubble. .
