Given:
Focal length(f) = 20 cm.
To find:
The radius of curvature of the mirror.
Solution:
Focal length(f) = 20 cm.
Radius of curvature(r) = ?
We know that,
Radius of curvature = 2× Focal length
∴ r = 2f
= (2×20)
= 40 cm.
∴ The radius of curvature of the mirror is 40 cm.
Answer:
The radius of curvature of the mirror is 40 cm.
