Article no. P1100300 | Type: Experiments
When using two extensive light sources, umbra and penumbra are formed behind opaque bodies.
- minimal preparation time
- light-intense halogen lamp
- easy teaching by using the demo board for demonstration
- ideal complement to analog student experiments by directly comparable devices
Observe umbra and penumbra with increasing distance of the object to the light source.
