Draw ray diagrams showing the image formation by a convex mirror when an object is placed
(a) at infinity (b) at finite distance from the mirror

Text Solution

Verified by Experts

(a) The virtual, erect and highly diminished image of the object forms at focus F behind the mirror when the object is placed at infinity.

(b) The virtual, erect and diminished image forms between focus F and pole P behind the mirror when the object is placed at finite distance from the mirror.
