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 formulas you are using.

< 12 of 14 Constants Part A A speaker fixed to a moving platform moves toward a wall, emitting a steady sound with a frequency of 225 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 6.00 Hz? Take the speed of sound to be 344 m/s. Express...
The beat detected on a moving platform.
A speaker fixed to a moving platform moves toward a wall,
emitting a steady sound with a frequency of 230 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.
Part A.) How fast should the platform move, vp, for the
person to detect a beat frequency of 2.00 Hz? Take the speed of
sound to be...
A speaker and microphone are attached to a cart moving toward a wall at speed LaTeX: v v m/s. The speaker sends out a constant tone, 236 Hz. The sound reflects off the wall and the reflected wave is detected by the microphone to have frequency 277 Hz. Taking the speed of sound in air to be 343.9 m/s, with what speed does the cart approach the wall? Give your answer to the nearest 0.1 m/s.
A bicyclist is moving toward a sheer wall while holding a tuning fork rated at 464 Hz. If the bicyclist detects a beat frequency of 6 Hz (between the waves coming directly from the tuning fork and the echo waves coming from the sheer wall), calculate the speed of the bicycle. Assume the speed of sound is 343 m/s.
Hint Mary sings a note with a frequency of 888 Hz as she runs toward a wall at a speed of 4.17 m/s. What is the beat frequency between the note she sings and its Doppler-shifted reflection from the wall? In other words, what beat frequency does Mary detect between hearing the sound of her voice directly and hearing the sound reflected from the wall? Mary detects two frequencies. One is the frequency of her voice. The other is the...
A sound source producing 1.00-{rm kHz} waves moves toward a stationary listener atone-half the speed of sound.The frequency that the listener will hear is2000 Hz.when the source is stationary and the listener moves towardthe source at one-half the speed of sound, the frequency that thelistener hear became 1500 Hz.Explain on physical grounds why thetwo frequencies differ.
