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.

As a bat flies toward a wall at a speed of 6.0 m/s, the bat emits an ultrasonic sound wave with frequency 30.0 kHz. What frequency does the bat hear in the reflected wave? Ship A is traveling 20 m/s due east. Ship B is traveling 15 m/s due west away from Ship A. Ship A sounds a horn with a frequency of 1500 Hz. What frequency does an observer on Ship A hear in the reflected wave from Ship...

Question: A cyclist ringing a bell with a frequency of 658 Hz rides towards a wall (Figure 1). The wall reflects the note back towards the cyclist. A sound meter detects a beat frequency of 13.0 Hz between the bell and the reflected tone as the cyclist rides. Assume the speed of sound in air is 337 m/s.

6) The sound from the whistle of a truck moving at 17.0 m/s toward a cliff reflects from the cliff and is heard by the driver of the truck. When it is parked at the side of the road, the whistle from the truck produces sound of frequency 2.267 kHz. As observed by the driver of the truck, what is the change in frequency the sound from the whistle due to the reflection? The speed of sound is 343 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...
