Relative to the size of the mirror, what happens to the size of your own face as you look at it and move away from the mirror?

Question2: You are standing in front of the mirror looking at the reflection of the face of the person standing behind you. The person backs away from the mirror. Relative to the size of the mirror, what happens to the size of the reflection of their face (as measured by you on the surface on the mirror)

Please help!

  1. Dont Back away- Zoom in then move away and DO your DAY!


  2. I assume you're talking about flat mirrors.  I'm mostly interested in the parabolic curved mirrors of a telescope.

    If you move twice as far away from a mirror, your image becomes 1/4 the size.  That's because the distance from your eye back to yourself doubles.

    If someone else moves twice as far, the distance triples, so the image goes to 1/3 size.

    This is relative to the mirror.  But if you walk up to the mirror to mark it, you've changed the distances.
