Question

Find the power of a lens whose focal length is 0.5 m.​

Answer 1

Answer:

A lens of focal length 0.5m has a power of 2D. If it is a converging lens (eg. Convex lens) then power will be positive i.e., +2D.

Please mark as branliest and like me

Answer 2

Given:- Focal length= 0.5

Formula:-

$power \: of \: lense = \frac{1}{focal \: length \: in \: meter}$

$power = \frac{1}{0.5}$

$power = \frac{10}{5}$

Power of the lens = +2D

It for converging lens or convex lens

It for converging lens or convex lensIf it diverging lens or concave lens then focal lenth is taken negative and power should be -2D.
