ID Code: L3-25
Purpose: To locate the image position for a concave mirror.
Description: Focus the TV camera on the image of its lens created by the concave mirror (or the "X" printed on a paper mounted on the lens). Move the ruler toward the mirror until it is in focus, demonstrating that the image is at that point. The pictures below show the meter stick too close to the camera (left), at the focus of the camera (center), and too close to the mirror (right). The background consists of a large amount of unrelated physics demonstration equipment.
