A concave spherical surface of radius of curvature R = 20 cm separates two media A and B having refractive indices mu_(A) =(4)/(3) and mu_(B) =(3)/(2) respectively. A point object is placed on the principal axis. Find the distance of the object from the surface so that its image is virtual when (a) the object is in medium A. (b) the object is in medium B.

A concave spherical surface of radius of curvature 10 cm separates two medium x & y of refractive index 4/3 & 3/2 respectively. If the object is placed along principal axis in medium X then

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?

If a ray of light takes t_(1) and t_(2) times in two media of absolute refractive indices mu_(1) and mu_(2) respectively to travel same distance, then

Three transparent media of refractive indices mu_(1), mu_(2), mu(3) respectively, are stacked as shown. A ray of light follows the path shown. No light enters the third medium. Then-
