Obtain as many harmonics as your arm can handle.
Generation of a standing wave by reflection from a fixed end.
A two person demonstration using a 2m (2cm diameter) steel spring. 1 One party acts as the fixed end, standing...
An aluminum rod, supported in the middle, rings for a long time in its longitudinal mode.
Longitudinal standing waves in solids.
A metal rod is not unlike an organ pipe with both ends open. Holding it exactly in the middle will...

The following is a sequence of experiments that can accompany a standard lecture on electromagnetic waves. The entire sequence is quite long and you may not want to do...
Rods attached to metal spine; transverse wave generator shows the reflection of waves free, fixed, terminated and transition boundaries.
Mechanical demonstration of transverse standing or traveling waves using the Shive wave machine.
Static 3-D stylized model of an electromagnetic wave, with two sets of sinusoidal fins at 90° representing the E and B fields.
The wave packet model consists of a wooden spine with E and B fins of 1cm wooden dowels. A plastic...

Various wave phenomena demonstrated with water waves: circular waves from point sources, plane waves from an array of point sources, change of...
In explaining the electron orbits in the Bohr atom, de Broglie's principle of particle wave duality allows you to treat the electrons as waves of wavelength nλ = 2πr where r is the radius of the orbit. Then the only orbits allowed are those...
Fifteen uncoupled simple pendulums of monotonically increasing lengths dance together to produce visual traveling waves, standing waves, beating, and random motion. One might call this kinetic art and the choreography of the dance of the...
What it shows: A room-size laser interferometer with audio signal output. A standing wave is produced whenever a wave is reflected back on itself. A resonant cavity requires a second reflection so that the twice reflected wave has the opportunity to be...
