Question

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

• A. $2m$
• B. $1m$
• C. $0.5m$
• D. $0.25m$

Answer 1

The correct option is B

$1m$

Step 1: Given

Object distance, $u=0.5m$

Image distance$=v$

Step 2: Determine the image distance

For a plane mirror, the object distance is equal to the image distance.

$\Rightarrow u=v=0.5m$

Step 3: Determine the required distance

The distance between the image and object is

$$\begin{gathered} v+u=0.5+0.5 \\ =1m \end{gathered}$$

Hence, option (B) is the correct option.
