Additional Info

• ID Code: L2-04
• Purpose: Show the nature of a virtual image.
• Description: This is a large-scale demonstration of a virtual image created by a plane mirror. The object and image are lab stands positioned at equal distances in front of and behind the mirror. It can be shown that the virtual image formed by the mirror lines up with the second, physical stand - the image is in the same location, as far behind the mirror as the real stand is in front of it.

  Alternatively, a single stand can be placed in front of the mirror, and strings attached to nails along the top. Invite student volunteers to stretch out the strings as rays that converge at the location of the image. Then show that the you can put the second stand at the point where the strings meet and it lines up with the image.
