Answer 2

An object is kept in front of the spherical mirror whose distance, u = 20 cm.

A virtual image is formed, whose distance, v= 15 cm.

Explanation:

As we know, the magnification, $m = -\frac{v}{u} = \frac{-15}{-20} = 0.75 cm.$

• The magnification of the image is 0.75 cm i.e., the image is virtual, erect, and small in size.
• And the type of mirror used is a convex mirror as it forms an image that is smaller in size.
