Answer:
 
 
 

Object at O, centre of curvature at C, virtual image at B. Pole at P. A is point of incidence. AP  is dropped. Refractive index of rarer medium n 1 and denser medium n 2 .

In parallaxial approximation A is very near to P thus PP ? 0

(Lens makers formula using concave and convex surfaces)

Let a ray of light from the object O incident upon a concave surface of radius R and come out of the convex surface radius R 2 . Let the rarer medium have a r.i. n 1 and denser medium n 2 .

Since the lens is thin thus PP ? 0

Let

OP= -u

OP=-v

Radius = -R 1

Applying the Gaussian formula for concave surface,
