Question

If an object is placed at a distance of $0.5\text{m}$ in front of a plane mirror, the distance between the object and the image formed by the mirror will be

• A. $2\text{m}$
• B. $1\text{m}$
• C. $0.5\text{m}$
• D. $0.25\text{m}$

Answer 1

The correct option is B $1\text{m}$

The virtual image formed by the mirror is at the same distance behind the mirror as the real object in front of it.

If distance of object from mirror $x_1=0.5\text{m}$
Then, distance of image from mirror $x_2=0.5\text{m}$
So, distance between object and image $x=x_1+x_2=0.5\text{m}+0.5\text{m}=1\text{m}$

$\begin{array}{c}\text{Note :- This question is asking you to find the distance of image from object.}\end{array}$
