In this demonstration, a frosted light bulb with a vertical arrow drawn on its surface, is operated at low voltage and placed behind a converging lens. The object distance from the lens is less than the focal length, thus the lens becomes a simple magnifier. The nature of the virtual image is observed as the light bulb is moved within the focal distance.
Equipment:
Converging lens
Lens holder
Frosted 110 V light bulb with arrow
Power supply (variac)
Connecting wires
Jack stand
