Question

The ratio of the focal length of spherical mirror to its radius of curvature is a) 0.5 b) 1 c) 2 d) 3

Answer 1

Answer:

0.5

Explanation:

Focal length is half radius of curvature and thus the ratio is 1:2 or 0.5

Answer 2

The ratio of the focal length of spherical mirror to its radius of curvature is 0.5.

Explanation:

The relationship between focal length and the radius of curvature is given by :

$R=2f$..........(1)

Where

R is the radius of curvature

f is the focal length of the spherical mirror

Dividing equation (1) by R. So,

$\dfrac{R}{R}=2\dfrac{f}{R}$

$\dfrac{f}{R}=\dfrac{1}{2}$

$\dfrac{f}{R}=0.5$

So, the ratio of the focal length of spherical mirror to its radius of curvature is 0.5. Hence, this is the required solution.
