Purpose: To determine the location of a real image in a complex lens-mirror system.
Description: A lens has a focal length twice that of a convex mirror. The lens is positioned at a distance of twice the focal length of the mirror (the focal length of the lens) in front of the mirror. An object is placed a distance of twice the focal length of the lens in front of the lens. The image position, at the same point as the object position, can be determined by calculation and verified by this demonstration. The photograph below shows the real, inverted image on the baffle.
