Geometrical Optics

  1. Apr 28, 2004 #1
    I just have a few questions on geometrical optics.

    1. Why do the hands of a clock move counterclockwise in a mirror?

    2. If you move farther away from a plane mirror, will you be able to see more of yourself or less?

    3. How do you decide if the image in a mirror is real or virtual?

    Thanks in advance for your help.

    1. Front and back are reversed in a plane mirror. The hands move te same way as they would when viewing the clock from the back

    2. Neither

    3. A real image can be viewed on a screen. If you can see an image on a piece of paper, it's real.
