Chladni's Plates with Violin Bow and Sand strips safeguarding the reliability of anyThere are many methods to demonstrate vibrations and waves in air columns, strings, springs etc. but an interesting investigation is the demonstration of vibrations in flat plates. In 1787 a scientist named Chladni studied the behaviour of fine sand sprinkled on flat plates when the plates were set into a natural vibration. To this day the study of vibration patterns on plates is performed in the same manner. The plate of metal or glass is supported
