Parabolic reflectors focus the light of the sun into a
focal point in which a piece of paper can even be set on fire.
Parabolic troughs have a focal line in which pipes or tubes, for
example, can be heated in a particularly efficient manner. In this
experiment, a black test tube that is filled with water is
illuminated with a 120 W reflector lamp and the effect of the
parabolic trough is studied based on various set-ups:
test tube in the focal line, out of the focal line, and set-up
without a parabolic trough.
- Part of a system solution - Easily expandable for further experiments
- easy teaching by using the demo board for demonstration
- Simplified implementation: all pre-settings already prepared
