Light: Reflection and Refraction

Refraction of ray of light through Convex and Concave Lenses:

Refraction of parallel ray:-

Convex lens1
Conccave lens1

A parallel ray converges at focus of a convex lens and diverges from the focus of a concave lens.

Refraction of ray passing through the Principal focus:

A ray passing through principal focus emerges parallel to the principal axis after refraction from a convex lens.

Convex lens2
Conccave lens2

A ray passing through the principal focus emerges parallel to the principal axis after diverging from a concave lens.

Ray passing through the optical centre of lens:
Convex lens3
Conccave lens3

Ray passing through the optical centre of convex and concave lens emerges in same direction without any deviation.

Converging lens:-

A convex lens is known as converging lens because parallel rays converge at its focus.

Converging lens
Diverging lens

Diverging lens:-

A concave lens is known as diverging lens because parallel rays diverge from its focus.
