Question

What will be the radius of curvature of a spherical mirror whose focal length is 5 cm?

Answer 1

Step 1: Given Data

focal length $f=5cm$

radius of curvature$=$ $r$

Step 2: Relation between the radius of curvature and focal length

$r=2f$

Step 3: Finding the value of the radius of curvature

$r=2\times 5cm$

$=10cm$

Hence, the Radius of curvature is $10cm$
