Speed of sound from stationary waves
Slide a microphone between a loudspeaker and a reflecting board, find nodes on the oscilloscope at five frequencies and determine the speed of sound from a graph of wavelength against 1/f.
This simulation supports preparation and data-analysis practice. It does not replace carrying out real practical work.
