Question

how is a spherical mirror used to converge a beam of light at a point ??​

Answer 1

Answer:

a beam of light parallel to the principal axis fall on a convex mirror, all the rays after reflection diverge. If the reflected rays are extended backwards, they appear to be metting at a point on the principal axis. This point is called the focus of the convex mirror.
