Question

Deduce the spherical surface equation by wave theory.​

Answer 1

Spherical lens is used by us in one way or the other. They are used in various places like our vehicle’s mirror, spectacles, etc. The spherical surface’s refraction is caused by the below reasons.

Explanation:

• Let us consider the spherical surface having the refraction of light.
• Refraction is nothing but the bending of a light wave, or the change in the direction of the light wave moving from one medium to another medium when there is a change in the speed of the wave.
• Let us imagine a figure with spherical surface with two refractive indexes indicated as n1 and n2.
• When the medium moves to the denser medium from the rarer medium, the bending of the ray becomes normal.
• The formed image has the curvature radius indicated as R and the spherical surface’s center will be C.
