1. A source moving with a speed 37 m/s, emits a sound wave with a frequency f = 377 Hz. Determine the frequency detected by a stationary observer if the speed of sound is v = 343 m/s and the source is moving towards the observer. 2.A stationary source, emits a sound wave with a frequency f = 428 Hz. Determine the frequency detected by an observer moving towards the source with a speed v = 43 m/s, if the...

9. An ambulance truck emits a sound with a frequency of 800 Hz. (the speed of sound in air at 20 Celsius is 343 m/s). (a) What is the frequency detected by a stationary observer if the ambulance truck moving 30 m/s toward the observer? (b) What frequency will b detected if the ambulance is moving 30 m/s away from the observer?

The siren on an ambulance is emitting a sound whose frequency is 2850 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...

7. You are standing still on a day when there is no wind. Four different sources of sound are moving relative to you (either directly toward you or directly away from you). State whether each source is moving toward you or away from you and state how rapidly (in m/s) it is moving relative to you. The speed of sound in air is 343 m/s. Explain your answers. (a) Source 1 emits sound of frequency 125 Hz, but the sound...
