Oscillation Apparatus

Wed, 15 Jul 2009 18:02:57 +0000

Oscillation and Wave Apparatus The development of the apparatus is based on the well-known Prytz Oscillating Apparatus. The components are a Plexi-glass tube, inside which a helical spring is hanging from the top, with a bowl loaded with a circular magnet. Surrounding the tube, a vertically adjustable circular induction coil that connects to for example the Function Generator F12 or F50. In General: With the induction coil connected to the function generator, the helical spring pendulum is set to vibrate - longitudinal oscillations - that moves up through the spring and is reflected from the fixed point of the spring at the top. The spring-particles are now influenced by both the incoming and the reflected wave. For specific drive frequencies a resonance case builds up. This is recognized as a standing wave on the spring in form of easy recognizable distribution of knots and bows - contraction and expanding of the spring windings. On the base of the apparatus there are three adjustment screws. When the spring-pendulum is fixed with the top bar on the tube, the adjustment screws are set, so that the spring-pendulum with bowl and magnet does not touch the tube. The spring pendulum must oscillate free from the tube.
