Two musicians are playing two pieces of the same instrument so that the sound produced by the first musician has a frequency of 1 kHz and the sound produced by the second musician has a wavelength of 0.15 m but otherwise the sound waves are in phase and equal in amplitude (20 Points). Use the speed of sound as 342 m/s under the conditions prevailing in the music hall:
a) What is the frequency at which the audience will hear rapidly rising and falling sound?
b) What is this frequency called?
