A hemispherical glass body of radius 10 cm and refractive index 1.5 is silvered on its curved surface . A small air bubble is 6 cm below the flat surface inside it along the axis. The position of the image of the air bubble made by the mirror is seen :

A glass hemisphere of radius 10 cm and mu=1.5 is silvered over its curved surface. There is an air bubble in the glass 5 cms from the plane surface along the axis. Find the position of the images of this bubble seen by observer looking along the axis into the flat surface of the atmosphere.

If a small air bubble of radius 0.1 mm is formed just below the surface of water, then the pressure inside the air bubble will be

A plano-concave lens is made of glass of refractive index 1.5 an the radius of curvature of its curved surface is 50 cm. What is the power of the lens?

A sphere made of transparent material of refractive index ( mu =3/2 )and of radius 50 cm has a small air bubble 10 cm below the surface. The apparent depth of the bubble if viewed from outside normally is
