Variable Vibrator

$217.80 $198.00

The Variable vibrator (in conjunction with an appropriate signal generator) can be used to clearly and easily provide mechanical vibrations (of a variable frequency and variable amplitude) along a length of line under tension.

The unit comes complete with a set of 50 gram slotted weights plus carrier rod and two lengths of line (of different mass per unit lengths) so that the effect of altering the tension on the line, the medium in which the wave is travelling and the frequency with which the waves are being generated, may be observed. Nodes and standing waves can be displayed so that the relationship between velocity, frequency and wavelength may also be investigated.  A stroboscope might also be used to stop the motion of the vibrating line. 

Instructions included.
