MCQ
Magnification produced by a concave lens is always :
  • A
    More than $1.$
  • B
    Equal to $1.$
  • ✓
    Less than $1.$
  • D
    More than $1$ or less than $1.$
✓

Answer

Correct option: C.
Less than $1.$
$\text{Magnification}=\frac{\text{Size of the image}}{\text{Size of the object}}$
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 $1.$
