Resonance tube at two consecutive standing wave positions.
Resonance tube at two consecutive standing wave positions.
A student uses a vertical resonance tube partially filled with water to determine the unknown frequency of a tuning fork. A standing sound wave is produced in the air column when the tuning fork vibrates near the open top of the tube. As the water level is lowered, the first two consecutive resonances occur at air column lengths of \(0.17\text{ m}\) and \(0.51\text{ m}\). Assuming the speed of sound in air is \(340\text{ m/s}\), what is the frequency of the tuning fork?
