|22 Resonant wave
Resonant springis suspended in a number of thin nylon threads (included). These are fitted to a plank which is mounted from the ceiling. The nylon threads are about 1,5 meters or custom defined.
A beautiful and spectacular exhibit. The stainless spring is loosely extended to about 10 meters. One end it is fastened to a wall, while the other is manouvered by the visitor.
The visitor can examine transversal and longitudinal waves, which travel similar to radio waves and sound waves.
This exhibit should preferably be exposed together with the Parabolic antennas and the Sound lens.
