Q1 FREE PREVIEW

The relation between radius of curvature R and focal length f of a spherical mirror is -
[PYQ 2025]

a

\(R=\frac{f}{2}\)

b

\(R=f\)

c

R=2f

d

R=4f

✓ Correct answer: a)

\(R=\frac{f}{2}\)

Explanation

The radius of curvature (R) of a spherical mirror is twice its focal length (f), which can be expressed as the formula R=2f. This means the focal length is half the radius of.
\(f=\frac{R}{2}\).
