Use the images to answer the question. The images show the pressure waves created by a passing sound source. Which image corresponds to what moment in time? (1 point) Responses The low-pitched sound corresponds to the sound source getting closer; its wavelength is shorter. The high-pitched sound corresponds to the sound source moving away; its wavelength is longer. The low-pitched sound corresponds to the sound source getting closer; its wavelength is shorter. The high-pitched sound corresponds to the sound source moving away; its wavelength is longer. The low-pitched sound corresponds to the sound source moving away; its wavelength is shorter. The high-pitched sound corresponds to the sound source getting closer; its wavelength is longer. The low-pitched sound corresponds to the sound source moving away; its wavelength is shorter. The high-pitched sound corresponds to the sound source getting closer; its wavelength is longer. The low-pitched sound corresponds to the sound source getting closer; its wavelength is longer. The high-pitched sound corresponds to the sound source moving away; its wavelength is shorter. The low-pitched sound corresponds to the sound source getting closer; its wavelength is longer. The high-pitched sound corresponds to the sound source moving away; its wavelength is shorter. The low-pitched sound corresponds to the sound source moving away; its wavelength is longer. The high-pitched sound corresponds to the sound source getting closer; its wavelength is shorter.
The low-pitched sound corresponds to the sound source getting closer; its wavelength is shorter. The high-pitched sound corresponds to the sound source moving away; its wavelength is longer.
A stationary source produces a sound wave at a frequency of 100 Hz. The wave travels at 1125 feet per second. A car is moving toward the sound source at a speed of 100 feet per second. What is the wavelength of the stationary sound source and the wavelength that a person in the car perceives? (1 point) Responses wavelength of the stationary source: 11.25 ft; perceived wavelength: 12.25 ft wavelength of the stationary source: 11.25 ft; perceived wavelength: 12.25 ft wavelength of the stationary source: 10.25 ft; perceived wavelength: 11.25 ft wavelength of the stationary source: 10.25 ft; perceived wavelength: 11.25 ft wavelength of the stationary source: 11.25 ft; perceived wavelength: 10.25 ft wavelength of the stationary source: 11.25 ft; perceived wavelength: 10.25 ft wavelength of the stationary source: 12.25 ft; perceived wavelength: 11.25 ft
wavelength of the stationary source: 11.25 ft; perceived wavelength: 12.25 ft
