A person stands 1 m in front of a plane mirror. The DISTANCE between the person and their image is:
A1 m
BDepends on size of person
C0.5 m
D2 m
Answer & Solution
Correct answer: D. 2 m
The image is as far behind the mirror as the object is in front — so 1 m behind. Distance from the person (1 m in front) to the image (1 m behind) is 1 + 1 = 2 m.
