Prove that `(-mu_1)/(u)+(mu_2)/(v) = (mu_2 - mu_1)/( R)` when refraction occurs from rarer to denser medium at a concave spherical refracting surface.

Discuss briefly refraction from rarer to denser medium at a concave spherical refracting surface.

Discuss refraction from denser to rerer medium at a convex spherical refracting surface.

The relation governing refraction of light from rarer to denser medium at a spherical refracting surface is

When refraction occurs from denser to……….., then (mu_2)/(mu_1) = …………. .

When reflection occurs from denser to………….., then (mu_(2))/(mu_(1)) = ……… .

When a light ray from a rarer medium is refracted into a denser medium, its

If mu_(v), mu_(r), mu_(b) are refractive indices of violet, red and blue, respectively, in a given medium, then

Figure shows figure three transparent medi of refractive indices mu_1, mu_2 and mu_3 . A point object O is placed in the medium mu_2 . If the entire medium on the right of the spherical surface has refractive index mu_1 , the image forms at O. If this entire medium has refractive index mu_2 the image form at O''.
