Properties of a concave mirror

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.
