A beam of light strikes a glass sphere of 20 cm diameter converging towards a point 40 cm behind the pole of the spherical surface.Fnd the position of the image,if the refractive index of glass is 1.5.

A small black dot is marked on the surface of a glass spehre (mu=1.5) and is viewed from the other side.If radius of the sphere is 15 cm,find the position of the image of the dot.

What is the Brewster angle for air to glass transition? (Refractive index of glass = 1.5.)

A small pin fixed on a table top is viewed from above from a distance of 50cm. By what distance would the pin appear to be raised if it is viewed from the same point through a 15cm thick glass slab held parallel to the table? Refractive index of glass = 1.5. Does the answer depend on the location of the slab?
