3.30 describe an experiment using an oscilloscope to determine the frequency of a sound wave

Method

- Plug a microphone into an oscilloscope
- Make a noise into the microphone (e.g. have someone sing a single note)
- Count the amount of oscillations per second (an oscillation is one complete wave, basically the wavelength)\

This is the frequency (as frequency is wavelength/time)
