i) A certain pipe consists of resonant frequencies of 434 Hz, 558 Hz, and 682 Hz, with no other resonant frequencies among these values.
Determine the fundamental frequency of this pipe?
Determine how long is this pipe?
ii) An ambulance traveling at 47 m/s approaches a car heading in the similar direction at a speed of 33 m/s. The ambulance driver consists of a siren sounding at 560 Hz. Determine at what frequency does the driver of the car hear the siren? (Suppose a temperature of 20° C.)
