A concave mirror produces three times magnified (enlarged) real image of object placed at 10 cm in front of it. Where is the image located?

Solution

Magnification produced by a spherical mirror is given by the relation,

m=

m=h_1/h_0=-u/v

Let the height of the object, h_0=h

Then, height of the image, h_1=-3h(image formed is real)

-3h/h=-v/u

v/u=3

Object distance, u= – 10 cm
= 3 × ( – 10) = – 30 cm
Here, the negative sign indicates that an inverted image is formed at a distance of
30 cm in front of the given concave mirror.
