A pipe is open at both ends. Its length is 22.81 cm. If I excite standing waves in the pipe by blowing air over one of its ends, I hear a pitch of 721.7Hz.

(a) Find the distance between the antinodes at the two ends of the pipe. This is not the same as the actual length of the pipe, since the antinodes are not exactly at the ends of the pipe. The speed of sound is 343 m/s.

(b) How far past the physical ends of the pipe do the antinodes extend? Assume that it is the same amount for each antinode.

(c) If I close one end of the pipe, what pitch will I hear? The node at the closed end is exactly at the position of the closed end. The antinode at the open end extends past the physical end of the pipe by the same amount found in part (b).
