Question

State and explain refraction through convex spherical surfaces.

Answer 1

Refraction through spherical surface Convention

1. The spherical surface must by very thin.

2. The object must be lie on the principle axis. The object is point object.

3. The angle made by object image and normal must be very-very small.

Convex surface—Real image

Equation (23) is the general equation for refraction through spherical surface.
