The siren on an ambulance is emitting a sound whose frequency is 2350 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 26.3 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 26.3 m/s and you are moving toward it at a speed of 16.0 m/s, find the wavelength and frequency of the sound you hear.
