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.

G3-03: SHIVE WAVE MACHINE - REFLECTION OF PULSES

Purpose: Demonstrate reflection of pulses from fixed ends and free ends.

G3-02: SHIVE WAVE MACHINE - SUPERPOSITION OF PULSES

Purpose: Demonstrate constructive and destructive interference using pulses.
