L7-42. Virtual Image - Mirror And Lens
Purpose
To calculate the position of a virtual image and the verify this by using parallax.◙
Equipment
Mounting pin parallax image, 30 cm focal length concave mirror, 30 cm focal length concave lens, and rod for object.
Setup Time
5 minutes
Images
Description
A concave mirror and a concave lens with the same focal length are positioned one focal length apart and the object post is positioned one focal length in front of the lens. The location of the image, behind the mirror, can be calculated and then verified experimentally using this demonstration. The image is located at the position of the rod at the left of the optical rail above (behind the mirror), which can be verified by parallax viewing between the image and the rod at that position.
