MCQ
The magnífication produced by a plane mirror is always ______.
- Amore than 1
- ✓1
- Cless than 1
- Dzero
✓
Answer
Correct option: B.
1
(B) 1
$\begin{array}{l}\text {Hint :}\quad m=\frac{h^{\prime}}{h}=1 \quad\left(\because \text { Here, } h^{\prime}=h\right)\\\text {or} \\ m=-\frac{v}{u} \\ \end{array} $
Here, $|v|=|u|$ and $u$ is negative while $v$ is positive.
$\therefore$ We get, $m=1$
