Answer 2

QUESTION:

Find out radius of curvature of spherical mirror if it's focal length is-20m..

ANSWER:

RADIUS OF CURVATURE :

It is the geometric centre of the sphere from which reflecting surface is a part. It is denoted with R.

FOCAL LENGTH :

Distance from the pole of the mirror to the focus.

We know that;

$radius \: of \: curvature = 2 \times focal \: length$

Now;

$radius \: of \: curavature = 2 \times ( - 20m) \\ radius \: of \: curvature = - 40m$

FINAL ANSWER:

$\huge\fcolorbox{purple}{yellow}{radius of curvature = - 40 m}$
