In geometrical optics 4 fundamental rays are used for construction of the light propagation.
- 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
All of the light paths described in the following lines should best be drawn:
- parallel rays
- vertex rays
- focal point rays
- midpoint rays.
Measure the distances MS and FS.
