Obtain an expression for refraction at a single convex spherical surface separating the two media having refractive indices `mu_(1) `(rarer medium) and `mu_(2) `(denser medium) i.e., a relation between `u, v, mu_(1),mu_(2)` and R.

Derive an expression for refraction at a single (convex) spherical surface, i.e., a relation between u, v, R, n_(1) (rarer medium) and n_(2) (denser medium), where the terms have their usual meaning.

If a ray of light is incident from rarer medium at an angle 45° on the surface which separates two medium having refractive indices 1 and sqrt(2) for rarer and denser medium, then angle of deviation of refractive ray with incident ray is

There are three optical media 1,2 and 3 with the refractive indices mu_(1) gt mu_(2) gt mu_(3) . (TIR rarr total internal reflection)

What is the relation between the refractive indices mu,mu_(1) and mu_(2) if the behaviour of light rays is shown in Figure.

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 diagram shows a spherical surface which separates two media of refractive index, mu_(1) and mu_(2) . Respectively. Now, a point object is placed on the principal axis as shown in the figure. Then

A plano convex lens fits exactly into a plano concave lens. Their plane surfaces are parallel to each other. If the lenses are made of different materials refractive indices mu_(1) and mu_(2) and R is the radius curvature of the curved surface of the lenses, the focal length of the combination is

If a convex lens of refractive index mu _l is placed in a medium of refractive index mu_m Such that mu_l > mu_m > mu_(air) then

Refraction takes place at a convex spherical boundary separating air-glass medium. For the image to be real, the object distance (mu_(g) = 3//2) Note Object lying in the glass.
