Suraj is observing his image in a plane mirror. The distance between the mirror and his image is 6 m. If he moves 2 m towards the mirror, then what will be the distance between Suraj and his image?

Explanation:

In the case of a plane mirror, the distance between the object and the mirror (d1) is same as the distance between image and mirror (d2).

so

if the distance between the mirror and his image is 6 m, then if he moves 2 m towards the mirror the distance between suraj and his image is

(6-2) = 4 m.

Hope it helps :)

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.

the answer is to check all of them! they all apply well at least i think so!
