A flutist assembles her flute (open-open tube) in a room where the speed of sound is 342 m/s. When she plays the note A (fundamental frequency), it is in perfect tune with a 440 Hz tuning fork. After a few minutes, the air inside her flute has warmed to where the speed of sound is 343 m/s. a. How many beats per second will she hear if she plays the note A as the tuning fork is sounded? b. Determine the length of the vibrating section of the flute when the speed of sound is 342 m/s. c. How far does she need to extend the "tuning joint" of her flute to be in tune with the tuning fork when the speed of sound is 343 m/s?
