A fire truck emits an 880 Hz siren. As the truck approaches an observer on the sidewalk, he perceives the pitch to be 950Hz. Approximately what pitch does he hear after the truck passes and moves away? Assume that the velocity of sound in air is 340m/s.
a) 800 Hz
b) 810 Hz
c) 820 Hz
d) 830 Hz
e) 840 Hz
A source produces a sound wave with a frequency of 800 Hz in air such that the velocity of the sound is 343 m/s. Thesource is moving away from a stationary observer at a rate of 15 m/s. Are the following ratios greater than one, equal toone, or less than one?
velocity of the sound measured by the observer/ (343 m/s)
frequency of the sound measured by the observer/ (800Hz)
wavelength of the sound as measured by the observer/ (0.429 m)
A mono-frequency sound source is fixed and an observer is moving towards it with velocity 35 m/s. An identical sound source is moving towards a stationary second observer. Find the velocity of the second source if both observers hear the sound of the same frequency. Assume that the speed of sound in the air is 343 m/s.
