A source of oscillations of frequency v0 = 1kHz moves through the normal to a wall with the speed u = 0.17m / s. In this same normal there are two fixed receptors P1 and P2, the sequence of their arrangement and the source F being the following: P1-F-P2. Which of the receivers records the pulsations and what is the frequency? The speed of sound v = 340m / s.

Question concept-Doppler effect in sound

when reflection takes place from a wall at rest then wall firstly behave like a observer at rest and after that a source at restso,p1 record pulsation of frequency of 1 HZ and p2 record no pulsation

A sound source with a frequency of 1800 Hz moves away 24 m / s from a reflective wall which also moves away from the source at 26 m / s. If the speed of sound is 343 m / s determine the frequency that detects the source of the reflected wave. (10 points)

A sound wave of frequency f=300Hz produced by a moving source 40m/s is observed by a stationary observer. The speed of sound in ambient air is 345 m/s. As the source moves toward the observer, how far does the source travel between subsequent wave pulses? What is the apparent wavelength of the sound wave as perceived by the observer? What is the frequency of sound perceived by the observer? Note, when the source is in motion, the speed of the...
