Answer 1

AnswEr

The distance of the man from the mirror is 6m.

In a plane mirror, the image distance is equivalent to the object distance. We are provided in the question, that :-

• image distance + object distance = 12m

Also, we know that, image distance is same as object distance of a plane mirror and we are asked to find the object distance. Which means :-

• 2 × object distance = 12m

• Object Distance = 6m.
