Demonstrates real and virtual image formation using concave and convex hand mirrors with a carbon filament lamp. Students observe inverted real images projected by the concave mirror and diminished virtual images in the convex mirror.
Figure 1:
The concave hand mirror mounted in its frame, with the adjustable lab stand for positioning. The projected filament image is visible on the blackboard behind the mirror.
Figure 2:
The carbon filament lamp in its shielded wooden box. The box directs light through the open face toward the mirror. The bright filament serves as the extended object for image formation.
