Consider a sphere of radius R made of glass of refractive index `mu`. A small object moves along the dismeter with a constant velocity u. Find the velocity of the image as seen by an observer outside when the object passes through center.

Consider a point object moving towards a stationary plane mirror with velocity 5m // s. Find velocity of image w.r.t object

A point object lies inside a transpatent solid sphere of radius 20cm and of refractive index n = 2 . When the object is viewed form air through the nearest surface it is seen at a distance 5 cm form the surface. Find the apparent distance of object when its seen through the farthest curved surface

A solid glass sphere with radius R and an index of refraction 1.5 is silvered over one hemisphere. A small object is located on the axis of the sphere at a distance 2R to the left of the vertex of the unsilvered hemisphere. Find the position of final image after all refractions and reflection have taken place.

There is a sphere of radius R and refractive index mu . At what distance from the surface of sphere should an object be placed so that real image is formed at the same distance from the sphere ?
