Homework Help: Mirror Optics- Measuring Virtual Image

  1. Jan 7, 2010 #1
    Recently, I asked my physics teacher how to measure the height of a virtual image behind a concave mirror. He said he wasn't exactly sure so he offered to give extra credit to anyone who could find information on how to do it. Is there anyone who can help?

    By drawing a scale diagram, you can find the height of the virtual image. You cannot from the virtual image on a screen. So actual measurement is not possible. Mathematically you can find the magnification and hence image distance.
