H3-03: REFLECTION OF PULSES IN TUBE

Purpose: Demonstrate the phase of pulses reflected from open ends and closed ends of a tube.

H3-02: STANDING SOUND WAVES - REFLECTION

Purpose: Demonstrate the origin of standing waves from one source and its reflection.

H3-01: STANDING SOUND WAVES - TWO SOURCES

Purpose: Demonstrate the origin of standing waves from two identical sources.

H2-28: FOURIER SYNTHESIZER - ADDITION OF WAVES

Purpose: Demonstrate addition of two sine waves with variable phase difference.

H2-25: QUINCKE'S INTERFERENCE TUBES

Purpose: Demonstrate interference of sound waves in a perhaps surprising way.

H2-24: AUDIBLE YOUNG'S EXPERIMENT - MIC AND SCOPE

Purpose: Demonstrate interference of sound with two coherent sound sources in a quantitative way.

H2-03: ACOUSTIC RADAR

Purpose: Illustrate how RADAR and SONAR work

H2-01: FOCUSING OF SOUND WITH CONCAVE REFLECTORS

Purpose: Demonstrate how sound waves can be focused by concave reflectors.

G3-52: ROPE WAVE GENERATOR - ROPE TENSION VS WAVELENGTH

Purpose: Observe the change in wavelength of a vibrating rope as the tension is varied.

G3-42: TORSIONAL WAVES

Purpose: Demonstrate wave phenomena such as traveling waves, standing waves, and reflection of waves.

G3-25: SLINKY ON LECTURE TABLE - IMPEDANCE MISMATCH

Purpose: Show partial reflections and dependence of wave speed on density of the medium.

G3-11: SHIVE WAVE MACHINE - RESONANCE ABSORPTION

Purpose: Demonstrate resonance absorption of wave energy by a mass-on-spring system.

G3-10: SHIVE WAVE MACHINE - BRANCHING

Purpose: Demonstrate branching and recombining with two wave machines in parallel.

G3-09: SHIVE WAVE MACHINE - FREQUENCY FILTERING

Purpose: Demonstrate frequency filtering through a "filter" consisting of four weighted crossarms and the interference from partial reflections they produce.

G3-08: SHIVE WAVE MACHINE - FABREY-PEROT INTERFEROMETER

Purpose: Demonstrate the mechanical analog of the optical Fabrey-Perot interferometer.

G3-07: SHIVE WAVE MACHINE - TAPERED TRANSFORMER

Purpose: Useful for obtaining a reasonably good impedance match between the two large segments of the Shive machine.

G3-05: SHIVE WAVE MACHINE - PARTIAL REFLECTIONS

Purpose: Show that a wave will be partially reflected at a point where the impedance changes.

G3-06: SHIVE WAVE MACHINE - IMPEDANCE MATCHING

Purpose: Show that no reflection occurs when the impedance of the load (absorber at right) matches the impedance of the wave machine.
