H1-27: SPEED OF SOUND - LISSAJOUS FIGURES

Category: H1 Nature of Sound

Purpose: Measurement of the speed of sound in air using Lissajous figures.

H4-18: LISSAJOUS FIGURES WITH SOUND

Category: H4 Music

Purpose: Demonstrate the relation between "consonance" (musical intervals) and frequency ratios.

H4-14: LISSAJOUS FIGURES - VOICE

Category: H4 Music

Purpose: Provide a Lissajous type display from a single vocal source.

H4-12: LISSAJOUS FREQUENCY MEASUREMENT

Category: H4 Music

Purpose: Show how frequencies can be matched using Lissajous figures.

G3-46: STANDING WAVES IN A WIRE LOOP

Purpose: Illustrate circular standing waves; to use as a model of stationary states in atoms corresponding to standing waves of electrons in Bohr orbits.

G3-45: RESONANCE OF WIRES

Purpose: Show standing waves in heavy wires fixed at one end.

G3-41: WAVE MODELS - PROJECTION
