Question

Derive the expression for refraction at single refracting surface

Answer 1

Answer:

Starting with an expression for refraction at a single spherical surface obtain an expression for lens maker's formula. ... τ= P1P2(thickness of lens). Let a point object O be placed on principal axis at a distance is u from P1. A ray OA travelling in rarer medium is incident on first surface of lens.
