Two speakers are playing two different but pure frequencies, fA = 110 Hz (an A two below Middle C) and fB = 124 Hz (the B one step higher than the first A), both with the same amplitude A.
a). What is the frequency (in Hertz) of the resulting short - period oscillations.
b). What is the frequency of the longer - period oscillation term?
