Problem 2: Two loudspeakers are placed 4.0 m apart on a stage. The
speakers generate identical sound waves when tested in a range of 20 Hz
to 20,000 Hz. A person sits directly in front of one speaker at a distance
of 10.00 m. The velocity of sound is 344 m/s.
a) What is the lowest frequency for which the person will hear a
b) What are the two highest frequencies for which the person will hear a
