Given:

The magnification of -0.7 of a concave mirror.

To find:

In order to obtain a magnification of -0.7 of a concave mirror where should an object be placed?

Solution:

The mirror equation is given by,

1/v + 1/u = 1/f

where, v, u and f  are the distances of the image and object from the mirror and the focal length respectively.

Magnification,  M = hi/ho = − v/u

where, hi and ho are the heights of the image and object respectively.

It is given that the magnification is - 0.7.

- 0.7 < 1

and u > v

Therefore, the object should be placed beyond the centre of curvature.
