Principle

In geometrical optics 4 fundamental rays are used for construction of the light propagation.

 

Benefits


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


 

Tasks

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.
