Sonometer (WA-7428)
After an overview of sonometer features, we demonstrate two approaches to making measurements in an investigation of wavelength vs frequency. One uses a sound sensor and FFT display to determine the frequency, while the other adjusts wavelength to achieve resonance with a tuning fork.

Measuring the Speed of Sound with an Echo
Students will first predict the speed of sound in the air of their classroom using a simple relationship accounting for temperature. Students will measure the time it takes a short pulse of sound to travel the length of a tube, reflect off the closed end, and return. Using this measurement, they will calculate the speed of sound and compare it to their prediction.
