Question

Linear magnification of a mirror has no units.

• A. True
• B. False

Answer 1

The correct option is A True

1. Linear magnification $m=-\frac{v}{u}$, where u is object distance from the mirror pole and v is image distance from the mirror pole
2. As both v and u have units of distance, linear magnification is unitless.
3. Hence the statement is true.
