Two musicians are comparing their clarinets. The first clarinet produces a tone that is known to be 442Hz . When the two clarinets play together they produce eight beats every 2.00 seconds.
Part A If the second clarinet produces a higher pitched tone than the first clarinet, what is the second clarinet's frequency?
