⏩The correct answer is (d) that is

$f = \frac{r}{2} \\ \\ 2f = r$

Hope it helps ✌

Answer 2

The correct answer is option (B) fR=2.

Explanation:

• For a spherical mirror, fR=2 is true.
• A curved mirror is a mirror with a curved reflecting surface.
• The surface may be either convex or concave.
• Most curved mirrors have surfaces that are shaped like part of a sphere, but other shapes are sometimes used in optical devices.
• Concave and convex mirrors are called spherical mirror because their reflecting surfaces are the parts of hollow sphere of glass.
