Homework Help: Help with height of image in a mirror

  1. May 23, 2012 #1
    An object which is 0.54m tall is located 1.23m in front of a plane mirror.
    How tall is the image as seen in the mirror?

    I know that the image seems to be 1.23m from the surface of the mirror and that the object seems to be 2.460m from the image.

    What equation do I need to use to figure out how tall the image is in the mirror.

    Thanks! I thought that that was the correct answer, but every time I entered .54m into the homework, the system told me that I need more digits. I tried 0.540m and that finally worked for me.
