Question

a convex lens of focal length is 10 cm ,calculate its power​

Answer 1

The power of the lens is 0.1 D

Step-by-step explanation:

Given data:

Focal length of lens "f" = 10 cm

As we know that power is inverse of the focal length.

Therefore, power=1/ focal length

P = 1/f = 1/10

P = 0.1 D

Thus the power of the lens is 0.1 D
