VIBRAAS - CHLADNI PATTERNS
Ref: 21-2901
The pattern is formed on an iron plate as a result of
vibrations generated by external vibration generator. In
principle, the sand or salt used for visualization of patterns
is forced off to areas of plate where amplitude of vibrations
is equal to zero (areas with no deflection). Plate has
numerous resonant frequencies and for each one there will
a unique pattern emerge from sand. Higher frequencies
generate more complex patterns. This set is simple tool for
demonstration of different vibration modes, nodal lines
and resonance.
