Refraction by Spherical Lenses

Lens is a transparent medium bounded by two refracting surfaces.

Types of lenses

(1) Convex or converging

convex lens
(2) Concave or diverging

conacve lens

Convex Lens

A lens having both spherical surface or one spherical and other plane surface.

It is thick in the middle and thin at the edges.

They are of 3 types:

(a) Bi-convex

Bi-convex lens
(b) Plane-convex

Plane-convex

(c) Concavo-convex

Concavo-convex

Concave lens

(a) Bi-concave

Bi-concave


(b) Plane-concave

Plane-concave
(c) Convexo-Concave

convexo-concave
