- Two trains approach each other, each train traveling at 26 m/s. The engineer on one train sounds his horn which has a frequency of 163Hz. What frequency does a passenger on the second train hear? Use 340 m/s for the speed of sound in airThe siren on an ambulance is emitting a sound whose frequency is 3650 Hz. The speed of sound is 434 m/s. (a) If the ambulance is stationary and you (the 'observer') are sitting in a parked car, what are the wavelength and frequency of the sound you hear? (b) Suppose that the ambulance is moving toward you at a speed of 36.8 m/s. Determine the wavelength and frequency of the sound you hear. (c) If the ambulance is moving toward you at a speed of 36.8 m/s and you are moving toward it at a speed of 22.0 m/s, find the wavelength and frequency of the sound you hear.A 3rd harmonic is being produced in a tube that is open at both ends. The tube is 3 meters long and the speed of sound is 340 m/s. What frequency will an observer hear?
- As part of a college physics lab. A car that is giving off a sound with a frequency of 350 Hz, is moving towards a group of students that are standing together (not moving). The students measure the sound coming from the car as 385 Hz. What is the speed of the car?A person stands directly in front of two speakers that are emitting the same pure tone. The person moves to one side until no sound is heard. At that point, the person is 7 m from one speaker and 7.2 m from the other. What is the frequency of the tone being emitted? Take the speed of sound to be 344 m/s, as usual.A bystander hears a siren vary in frequency from 590 Hz to 368 Hz as a fire truck approaches, passes by, and moves away on a straight street. What is the speed of the truck? (Take the speed of sound in air to be 343 m/s.)
- A fire engine siren emits sound at 1260 Hz. The fire engine is driving down the street toward you at 29 m/s. (The speed of sound in air is 343 m/s.) What frequency sound do you hear? What frequency sound do you hear after the fire engine passes you?A guitar string produces a musical note with a wavelength of 78.0 cm. If the speed of the sound in air is 347 m/s, what is the frequency of the note? * 445 Hz 0.29 Hz 290 Hz O 4.4 Hz O 29 kHzA sound wave traveling in air has a frequency f and wavelength λ. A second sound wave traveling in air has wavelength λ/ 2. What is the frequency of the second sound wave?
- If a stationary dolphin emits a call at a sound frequency of 53 kHz. The sound wave reflects off a fish moving directly towards the dolphin. And the sound wave echo returns at a frequency of 55 kHz. What is the speed of the fish? The speed of sound is 343 m/s.A truck travelling west at 60 m/s sounds it's 440 hz horn as it passes a stationary observer. What frequency does the observer hear as the car approaches and recedes?A stationary police car emits a sound of frequency 1200 HzHz that bounces off of a car on the highway and returns with a frequency of 1260 HzHz. The police car is right next to the highway, so the moving car is traveling directly toward or away from it. What frequency would the police car have received if it had been traveling toward the other car at 23.0 m/sm/s ?
