Question

nitika observing her image in a plane mirror .the distance between the mirror and her image is 4m .what distance of nitika from the plane mirror? if she moves 1 metre towards the mirror ,then what is the distance between nitika and her image.

Answer 1

When the distance between mirror and image is 4m then the distance between the mirror and Nitika is also for me because the distance between mirror and the image formed and the distance between the mirror and the object is always the same.

When she moves 1 m towards the mirror then the distance between Nitika and mirror becomes 3m

So,

the distance between the image and mirror will be 3m

and the distance between Nitika and the image formed will be 3m+3m=6m
