Question

The magnification produce by a concave mirror is less than 1.Write the information about image formed by this statement.

Answer 1

Dear Student

$M=\frac{I}{O}=-\frac{v}{u}$
Since magnification is positive, the image formed is virtual and erect, that is formed behind the mirror as in concave mirror object distance is always positive quantity.

Also, since the magnification is less than 1, the image size is smaller than the object size
