Physics
Draw suitable diagrams to illustrate how a beam of light incident parallel to the principal axis is reflected by:
(a) a concave mirror and
(b) a convex mirror.
Answer
(a) A beam of light incident parallel to the principal axis of a concave mirror, after reflection meets at a point called focus of the mirror.
(b) A beam of light incident parallel to the principal axis of a convex mirror, after reflection appears to meet at a point called focus of the convex mirror.
