d. length of the air column​

Answer 1

Answer:

To change the pitch of the sound, some instruments such as the flute have holes in the tube. The musician covers the holes with her fingers. Covering and overcovering the holes changes the path of the air, changing the air chamber size, and therefore the pitch of the note.
