Question

✌️Derivation✌️

Derive the formula for refraction through a convex spherical surface !!​

Answer 1

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.

Answer 2

Explanation:

Let O be a point object or it's principle axis kept in a rarer medium first incident ray travelling through C is normal to the spherical surface. Therefore it will not deviate and goes along PX another mident ray OA will refract at point A and it bends towards the normal.
