Question

If you stand 3.0 m in front of a flat mirror, how far away from you would your image be in the mirror?

Answer 1

`6m`.

Explanation:

If you are standing `3m` from a mirror, then the mirror reflects what you see.

Thus, the mirror reflects an image that is `3m` away from it.

This results in an apparent image that is `6m` from you.

This can be visualized in the image below.

Let's say the "P" is you, and the distance from you and the mirror is `3m`. By looking at the mirror, the image produces a reflection of you - the "P" that is `3m` away, resulting in a relfection that is 6m away from you.

Hope this helps :)
