(a) A point object, O is on the principle axis of a spherical surface having a radius of curvature, R. Draw a diagram to obtain the relation between the object and image distances, the refractive indicess of the media and the radius of curvature of the spherical surface.

A spherical surface of radius R ssparates two media of refractive indices mu_(1) and mu_(1) as shown in figure., Where should an object be placed in medium 1 so that a real image is formed in medium 2 at the same distance?

The image of an object placed in air formed by a convex refracting surface is at a distance of 10 m behind the surface. The image is real and is at (2^(rd))/(3) of the distance of the object from the surface. The wavelength of light inside the surface is (2)/(3) times the wavelength in air. The radius of the curved surface is (x)/(13)m . The value of 'x' is _________.

Show that for refraction at a concave spherical surface (separating glass-air medium), the distance of the object should be greater than three times the radius of curvature of the refracting surface for the image to be real.
