The siren on an ambulance is emitting a sound whose frequency is 2250 hz. the speed of sound is 343 m/s. (a) if the ambulance is stationary and you (the "observer") are sitting in a parked car, what are the wavelength and the frequency of the sound you hear? (b) suppose that the ambulance is moving toward you at a speed of 26.6 m/s. determine the wavelength and the frequency of the sound you hear. (c) if the ambulance is moving toward you at a speed of 26.6 m/s and you are moving toward it at a speed of 11.0 m/s, find the wavelength and frequency of the sound you hear.
