Question

A convex mirror has a radius of curvature of 22cm if an object is placed 14cm away from the mirror then its image is formed at

Answer 1

Radius of curvature = 22cm

focal length of mirror(f)=1/2×22=11cm

object distance(u)=14cm

let image distance be v

USING MIRROR FORMULA

1/f=1/u+1/v

1/11=1/14+1/v

1/11-1/14=1/v

14-11/154=1/v

3/154=1/v

v=154/3

v=51.3 cm

IMAGE WILL FORMED AT 51.3cm
