Question

An object placed $2m$ from a plane mirror is shifted by $0.5m$ away from the mirror. What is the distance between the object and its image?

• A. $2m$
• B. $1.5m$
• C. $5m$
• D. $3m$

Answer 1

Answer: (C)

$5m$

After shifting object 0.5m away from mirror, the distance between the object and the mirror = 2.5 m.

Hence, distance between object and image is 2x2.5 m = 5 m.
