Purpose: Locate both real and virtual images of a convex lens
Description: The lens on the lecture table forms either a real or a virtual image of the number 3 on the homework tray to the right of the table. The TV camera is then focused on that image. Moving the scale to the side of the optic axis, the image location will be the position at which the scale is in focus. This technique can be used to locate either a real or a virtual image.
