ID Code: L3-21
Purpose: Optical illusion with real image of a concave mirror
Description: A light bulb is mounted upside down in the black box and positioned at the center of curvature of the mirror. The image is real, inverted, and located at the same position as the object, as seen in the photograph. The bulb can be unscrewed and removed, but it remains lit in the socket! This has a limited field of view, but can be rotated on the stand so that all viewers can see it.
Availability: Available
