## Question:

If you have three waves corresponding to the lowest three frequencies of vibrations of a 30 cm air column, what is the wavelength of the standing wave in each case? What frequency is heard in each pipe? The speed of sound in air is 331 m/s.

## Standing Waves:

Standing waves can be manifested physically through musical instruments. For example, an organ produces sound through the vibration of air molecules within itself, and the frequency is dependent on the length of the pipe of the corresponding key for the organ.
