Question: A flute is designed so that it produces a frequency of 261.6 Hz when all the holes are covered and the temperature is 20 degree C. Consider the flute as a pipe that is open at bothe the ends. find the length of the flute assuming the middle C as the fundamental frequency. (a) A second player nearby in the colder room also attempts to play middle C on an identical flute. a beat frequency of 2.96 Hz is heard when both the flutes are playing. what is the temperature of the second room?
