Question

if a boy moves 1M backward ,find the distance between the image and the boy​

Answer 1

the boy moves about 2 meter

Answer 2

I assume the initial position of the boy to be very close near the mirror.

Now, the boy moves 1 metre from the mirror, the image also moves the same distance on the other side.

So the diatance between the position of the boy and the position of the boy's image = 1m+1m =2m
