A sound source producing 1.00-{rm kHz} waves moves toward a stationary listener atone-half the speed of sound
A. A sound source producing 2.90 kHz waves moves toward a stationary listener at one-half the speed of sound. What frequency will the listener hear? Express your answer in hertz. B. Suppose instead that the source is stationary and the listener moves toward the source at one-half the speed of sound. What frequency does the listener hear? Express your answer in hertz.
If a 1.00-kHz sound source moves at a speed of 53.0 m/s toward a listener who moves at a speed of 28.0 m/s in a direction away from the source, what is the apparent frequency heard by the listener? (Use 343 m/s as the speed of sound in air.) A) 795 Hz B) 937 Hz C) 1000 Hz D) 1086 Hz E) 1279 Hz
The sound wave source moves away from a stationary listener at 80 m/s. The speed of sound is 340 m/s and the frequency of sound is 200 Hz. a) Find the wavelength of sound waves between the source and the listener. b) Find the frequency heard by the listener.
A source of sound waves of frequency 1.2 kHz is traveling through the air at 0.45 times the speed of sound. (a) Find the frequency of the sound received by a stationary observer if the source moves toward her. Hz (b) Repeat if the source moves away from her instead. Hz
An airplane traveling at half the speed of sound emits a sound of frequency 4.43 kHz. (a) At what frequency does a stationary listener hear the sound as the plane approaches? (b) At what frequency does a stationary listener hear the sound after the plane passes?
An airplane traveling at half the speed of sound emits a sound of frequency 5.97 kHz. (a) At what frequency does a stationary listener hear the sound as the plane approaches? 11.94 kHz (b) At what frequency does a stationary listener hear the sound after the plane passes? 2.99 Your response differs from the correct answer by more than 10%. Double check your calculations. kHz
A sound source is moving toward a listener at a velocity of 75 m/s. the listener is moving away from the sound source at 55 m/s. What frequency will the listener hear if the source frequency is 512Hz? Take 344 m/s as the speed of sound.
6. -M10 points SerCP10 14.P.024. An airplane traveling at half the speed of sound emits a sound of frequency 4.66 kHz. (a) At what frequency does a stationary listener hear the sound as the plane approaches? kHz (b) At what frequency does a stationary listener hear the sound after the plane passes? KHz
Tutorial Sound Waves . A sound source which produces sound of frequency 300 Hz moves along a straight line and passes by a stationary observer. The observer notices that the frequency of sound heard change Speed of sound in air 330 m s-1] 0when the sound is moving away from him. Determine the speed of the sound source. its siren emitting a sound of frequency 600.0 Hz moves with a speed of me that the speed of sound is 345...
A speaker fixed to a moving platform moves toward a wall, emitting a steady sound with a frequency of 215 Hz . A person on the platform right next to the speaker detects the sound waves reflected off the wall and those emitted by the speaker. How fast should the platform move, vp, for the person to detect a beat frequency of 1.00 Hz ? Take the speed of sound to be 344 m/s. Please be specific in explaining what...
