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). Please write out the full equation which describes the superposition between these two waves, as a product of two cosine terms (leave the equation in symbolic form, without plugging in numbers for the frequencies).

b). What is the frequency (in Hertz) of the resulting short - period oscillations.

c). What is the frequency of the longer - period oscillation term?
