Spectral sounds: investigating the spectrum of sound and wave phenomena

​This resource describes how a frequency analyser app can be used to investigate the properties of sound created by a variety of musical instruments and comparing these with simpler sounds from, for instance, tuning forks. Students use a smart device such as a tablet as a measuring and recording device, and may save screen shots of the wave patterns created as images for later comparison, or to print as part of a display.
