A mirror diverges a beam of parallel light rays after reflection.
A concave mirror can converge parallel beams of light at one point. But rays originating from the focus after reflection does not always travel parallel to the principal axis.
Describe with a suitable diagram, how a convex mirror diverges a parallel beam of light rays. Mark clearly the pole, focus and centre of curvature of convex mirror in this diagram.
If a parallel beam of light is incident on a plane mirror, the reflected rays will be
Why do rays in a parallel beam of incident light not remain parallel to each other after reflection from a rough surface?
