A siren emitting a sound of frequency 1003 Hz moves away from you toward the face of a cliff at a speed of 12.0 m/s. Take the speed of sound in air as 334 m/s. (a) What is the frequency of the sound you hear coming directly from the siren
Answers: 2
would be:
, 
is the speed of sound in the air.
is the speed at which the source moves away from the observer.
is the frequency at the source.
.
. That corresponds to a period of 
.
.
. In the 
away from the observer. It would take an extra 
for the sound to cover that extra distance. 
to the observer.
. (Same as the answer from the formula.)

Wo audio speakers are placed on a vertical rail. speaker a is placed at head-level while speaker b is place at some variable height, \delta yδy, above speaker a. both speakers receive simultaneous input from a sine-wave generator so the speakers each produce a pure sinusoidal sound wave with a wavelength of 0.531 meters. calculate the lowest height that speaker b can be placed above speaker a to produce a minimum of sound heard by person standing \delta x = 7.86δx=7.86 meters directly in front of speaker a.
