Question

A diverging mirror forms a virtual image of height 1cm of an object of height 4cm placed 20cm away from the mirror. Calculate the image distance.

Answer 1

Converging mirror is actually concave mirror!

hi = 4cm

ho = 1cm

u=-20cm

(a) v=?

hi/ho=-v/u

where,

hi=height of the image

ho=height of the object

v=distance of the image from the mirror

u=distance of the object from the mirror

4/1=-v/-20

4 = v/20

v = 80cm
