Question

Magnification of the concave lens is:

• A. Equal to 1
• B. Less than 1
• C. More than 1
• D. More than 1 and less than 2

Answer 1

The correct option is B Less than 1

Magnification = $\frac{heightofimage\left(h^{\prime }\right)}{heightofobject\left(h\right)}$
In case of concave lens it always form virtual and erect image,the magnification is always positive because the image formation and object placed are at same side of the lens.

Magnification of a concave lens is less than 1 meaning the image is smaller than object .
