*86. GO The siren on an ambulance is emitting a sound whose frequencyis 2450 Hz. The speed of sound is 343 m/s. (a) If the ambulance is sta-tionary and you (the “observer") are sitting in a parked car, what are thewavelength and the frequency of the sound you hear? (b) Suppose thatthe ambulance is moving toward you at a speed of 26.8 m/s. Determinethe wavelength and the frequency of the sound you hear. (c) If the ambu-lance is moving toward you at a speed of 26.8 m/s and you are movingtoward it at a speed of 14.0 m/s, find the wavelength and frequency of thesound you hear.

(a) Here, both the ambulance and the observer are at rest. Hence, both the frequency will be the…
