Question

write lens maker's formula and explain the terms​

Answer 1

Answer:

The lens maker formula gives the relationship between focal length, radius of curvature and the refractive index of the lens.

Mathematically it is given as :

Where,

F is the focal length

n is the refractive index

are the radius of curvature of the lens

In case of converging lens :

is positive

is negative

F is positive

In case of diverging lens :

is negative

is positive

F is negative.

Hence, this is the required solution
