Glass tube for demonstrating standing sound waves and calculating wavelengths of sound using cork powder in a method devised by Kundt.Cork powder is spread evenly throughout the tube by means of a filler chute. Then a sound source, e.g. a whistle, a 1700 Hz tuning fork (U10115) or a horn speaker (U8432680), is used to excite the powder into a regular pattern of nodes and antinodes. The effective length of the tube can be altered by means of a piston.Length: 600 mmExternal diameter: 20 mmInternal diameter: 17 mmContents:1 Glass tube with funnel1 Plunger1 Filler chute1 Whistle1 Bottle of cork powder
