उत्तर
Less than 1:
Magnification= `"size of the image"/"size of the object "`
From the formula, it is clear that the magnification varies directly with the size of the image. The image formed by a concave mirror is always smaller than the size of the object. Therefore, the magnification of a concave mirror is always less than 1.
