A man standing in front of a plane mirror finds his image at a distance 6 metre from himself. What is the distance of man from the mirror?

उत्तर
Distance between man and his image = 6m
Distance between man and mirror + distance between mirror and image = 6m
But, Distance between man and mirror (object distance) = distance between mirror and image (image distance)
Therefore, distance of man from mirror = 6/2 = 3m
