New standing waves are set up in a plastic cord. The speed can be adjusted to vary the number of nodes in the standing wave pattern by a signal generator. Tension can be adjusted with different masses attached to the cord over the pulley.

setup time: < 10 minutes

Old Standing waves are set up in a cord. The rotator speed can be adjusted to vary the number of nodes in the standing wave pattern. Tension can be adjusted with different masses attached to the cord over the pulley. The rotator should be clamped to the table with a 'C' clamp.

setup time: < 10 minutes

Demonstration of transverse wave motion. Rods are connected via central wire that propagetes a disturbance bewteen them.

setup time: < 5 minutes

Plastic and metal

setup time: < 5 minutes

Masses on Springs to demonstrate simple harmonic motion.

setup time: < 5 minutes

The battery powered sound source is swung in a large vertical circle. Viewed from the plane of the circle, the frequency periodically increases and decreases. The 'nurf' ball protects the sound source and audience

setup time: < 5 minutes

Beats Frequencies of two interfering sound waves are displayed on the oscilloscope. The TV camera is used to display the scope on the LDC projector.

setup time: ~ 15 minutes

Bell rings when jar is full of air. Once pumped out with vacuum pump, it is no longer audible.

setup time: 10 minutes

Pump the balls down with a vacuum pump to demonstrate the strength of the pressure pushing on the outside from atmosphere. Handles allow students to pull on it, or to attach weights.

setup time: < 5 minutes

Electrical heaters force rising air through two glass tubes of the same length. Use care with the electrical connections.

setup time: 0 minutes

Fill tube with flammable gas (!), attach speaker to diaphram end, light the gas coming out of the small holes on top. Produce a tone with the associated audio amp, and the sinusoidal wave pattern is visible in the flames above the tube.

setup time: < 15 minutes

Attach to a stand with a rod clamp. Apply 0-2.5 VDC to the terminals and the wooden plate moves in line with the long axis of the generator at sufficient frequency to demonstrate ripples/waves in a tank of water.

setup time: < 15 minutes

Project the image of the ripple tank onto the screen for students to see.

setup time: 10 minutes

Various size/frequency forks.

setup time: < 5 minutes

Variable speed and RPM counter.

Various pipe organ pipes, variable (slide) tone generators, and note-boxes with tuning forks on top.

setup time: < 5 minutes

Put various objects inside, and pull vacuum from the copper tube attached.

setup time: < 5 minutes

setup time: < 5 minutes
