A) Approximately how long should an organ pipe open at one end and closed at the other be if the pipe is intended to produce a fundamental note of frequency 300 Hz? Take the speed of sound to be 340 m/s. B) What would be the frequency of the third overtone of the pipe of part A)? C) On a lower temperature day the speed of sound might be 320 m/s. Find the frequency of the fundamental note produced by the pipe on such a lower temperature day.
