Question

A convex mirror has focal length of 15 cm. An object is placed at 20 cm from the pole of this lens. The nature of the image formed will be

Answer 1

Explanation:

V= UF/(U-F). U= 20cm F = 15cm

V= 20*15/(20–15) =+60cm

Magnification M = -(V/U) = - 60/20 =- 3

So V=60cm, virtual inverted and enlarged image will be formed behind the mirror at a distance of 60cm
