Converging Lens - Magnifier

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
