Question

The powe
power of
of a a convex lens of focal length
25 cm is how to solve
​

Answer 1

Answer:

Formula 1.) Focal length=1/2×radius of curvature

Formula 2.) Radius of curvature=2× Focal length

Hence, in this question we have the focal length so to find out

the radius of curvature we will use second formula

Step-by-step explanation:

Given: 25cm focal length

According to the Question:

Radius of curvature=2×Focal length

Radius of curvature= 2×25cm= 50 cm

Answer= 50cm
