Question

What factors decide the frequency of vibration of an air column?

Answer 1

1. The instruments in which sound is produced by the vibrations in air column are called wind instruments e.g. flute, shehnai, etc.
2. The frequency depends on the length of the air column.
3. The frequency varies inversely with the length of the air column.
4. Longer the air column, the less will be the frequency of the sound produced.
5. Therefore, the frequency of vibration of an air column depends on the length of the air column.
