Speed of Sound (9-12)

NOISE

Speed of Sound (9-12)

Noise: Speed of Sound participants will learn about motions and forces and the interactions of energy and matter as they use the principle of resonance to set up an experiment in the classroom to measure the speed of sound in air. The speed of sound will be calculated using the standard relationship between velocity, frequency and wavelength.

A second activity challenges students to produce longitudinal and transverse waves in a spring. They will measure wavelength, amplitude and the period of a transverse wave.
