Question

derive an expression for refraction at a single curved surface.​

Answer 1

Answer:

Every one of us has used the spherical lenses in some way or the other. The lens we use in spectacles, the mirror of our vehicle, is nothing but the spherical surface. But do you know what causes refraction in the spherical surface? Let us study in detail about spherical surface and also about refraction in lenses.

Answer 2

answer:

There is an object O and a ray of light from the object O is incident on the spherical mirror. Since it is moving from a rarer medium to a denser medium, the ray bends towards the normal. An image is formed and radius of curvature of a spherical surface is R with the center C of the spherical surface
