Question

The magnification produced by a plane mirror is $+1$. What does this mean?

✓

Answer

Solution:
Here, $m=+1$
As,$m=\frac{h \prime}{h}$
$\frac{h \prime}{h}=+1$
$\therefore h^{\prime}= h$
So, the size of the image is equal to the size of object.
Further, the positive (plus) sign of $m$ indicates that the image is erect and hence virtual.
Again, $m=-\frac{v}{u}$ and $m=+1$
$\therefore-\frac{v}{u}=1$
$\therefore v=-u$
This shows that the image is formed behind the mirror and the distance of the image from the mirror equals that of the object from the mirror.
