Standing waves

Wb-1 The Melde' Experiment

Published: Tuesday 14 March 2006

To demonstrate standing waves on a string.

Wb-2 Kundt's Tube

Published: Tuesday 14 March 2006

To demonstrate standing waves in a closed pipe using fine particles (cork dust) to display the characteristic modes.

Wb-3 The Gas Tube

Published: Tuesday 14 March 2006

To demonstrate standing wave patterns in a pipe using sound waves and gas jets to indicate the pressure profile.

Wb-4 The Chladni-Vibrating Plate

Published: Tuesday 14 March 2006

To demonstrate the Chladni figures i.e. the vibration modes of thin plates

Wb-5 Chladni Figures (Acoustically driven)

Published: Tuesday 14 March 2006

To demonstrate the modes of vibration of a plate.

Wb-6 The Monochord (The Sonometer)

Published: Tuesday 14 March 2006

To demonstrate the fundamental law of vibration of a stretched string.

Wb-7 Vibrations of a Rod

Published: Tuesday 14 March 2006

To demonstrate transverse vibrations in a rod.

Wb-8 Toothbrush Wave Generator

Published: Tuesday 05 June 2007

To demonstrate standing waves on a string using an electric toothbrush as the vibrating source

Wb-9 Circular Standing Waves (The Ring of Fire)

Published: Wednesday 23 September 2009

To demonstrate circular standing waves in a pipe using sound waves and gas jets to indicate the pressure profile. May be useful when discussing the Bohr theory of the atom and the quantization of electron orbits.
