Question

An object is kept at a distance of $0.5m$ in front of the plane mirror. The distance between the object and the image is:

• A. $0.5m$
• B. $1m$
• C. $0.25m$
• D. $0.75m$

Answer 1

The correct option is B $1m$

The image is formed at the same distance from the plane mirror as the object's distance from the mirror. Also, the image is formed on the opposite side as that of the object.
Hence, distance between the image and the object is the sum of the object distance and the image distance.
Hence, it is equal to:
$0.5+0.5=1m$
