A flutist assembles her flute in a room where the speed of sound is 342 m/s. When she plays the note A, 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 345 m/s. Part A How many beats per second will she hear if she now plays the note A as the tuning fork is sounded? Part B How far does she need to extend the "tuning joint" of her flute to be in tune with the tuning fork?

Interference of sound

Seiche

A seiche is an oscillating standing wave in a body of water. The term seiche pronounced saysh) can be understood by the sloshing of water back and forth in a swimming pool. The same phenomenon happens on a much larger scale in vast bodies of water including bays and lakes. A seizure can happen in any enclosed or semi-enclosed body of water.

Question

A flutist assembles her flute in a room where the speed of sound is 342 m/s. When she plays
the note A, 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 345 m/s.
Part A
How many beats per second will she hear if she now plays the note A as the tuning fork is
sounded?
Part B
How far does she need to extend the "tuning joint" of her flute to be in tune with the tuning
fork?
