The pan flute is a musical instrument consisting of tubes closed at the bottom and of different lengths, except for the shortest, in which the bottom end is open. When the musician blows over the top open ends (all tubes have an open-top end), each tube plays a different note. The longest pipe has a length of 0.4m and the shortest 0.2m. What are the frequencies of the 2nd stationary wave model produced by the longest and shortest pipes? The speed of sound is 330m/s. A) 206HZ (longest pipe) and 413HZ (shortest pipe) B) 413HZ and 1238HZ C) 619HZ and 1650HZ D) 619HZ and 825HZ

Question

The pan flute is a musical instrument consisting of tubes closed at the
bottom and of different lengths, except for the shortest, in which the bottom end is open. When the musician blows over the top open ends (all tubes have an open-top end), each tube plays a different note.

The longest pipe has a length of 0.4m and the shortest 0.2m.

What are the frequencies of the 2nd stationary wave model produced by the longest and shortest pipes?

The speed of sound is 330m/s.

A) 206HZ (longest pipe) and 413HZ (shortest pipe)
B) 413HZ and 1238HZ
C) 619HZ and 1650HZ
