Respuesta :
The effective length of the tube is responsible for determining the frequency of vibration of the air column in the tube within a wind instrument.
Answer;
B. Effective length of the tube.
Explanation;
- Most wind instruments are of either the open-open tube or the open closed tube type. Open ends of the tubes makes contact with the outside, atmospheric air.
- At an open end, when the air is disturbed in the wind instruments, the air vibrates with a variety of frequencies, however the frequencies that correspond to the natural frequencies will persist.
- Effective Length of the tube is responsible for determining the frequency of vibration of the air column in the pool with in a wind instrument.
