A sound wave in air has a frequency of 485 Hz. If the crests of the wave are 0.701 m apart, what is the speed of the wave?
A sound wave has a frequency of 704 Hz in air and a wavelength of 0.55 m. What is the temperature of the air? Assume the velocity of sound at 0◦C is 330 m/s. Answer in units of ◦C.
A sound wave has a frequency of 680 Hz in air and a wavelength of 0.48 m. What is the temperature of the air? Assume the velocity of sound at 0◦C is 330 m/s. Answer in units of ◦C.
One foggy morning, when the temperature of t he air was 19 degrees calcius, Kenny is driving his speed boat toward the Brant Point Lighthouse at a speed of 15 m/s as the fog horn blows with a frequency of 180 Hz. What frequency does Kenny hear as he moves?
A water wave has a frequency of 10 Hz and a length of 2.5 meters. What is the period of these waves? What is the wave velocity? What is the distance (in meters) traveled by a sound wave in 22 seconds as the wave moves through Air? A steel rail A 600 Hz sound has a velocity of 1087 ft/s in the air and 4920 ft/s in water. Find the wavelength of this sound: In air In water
9 Two cars rapidly approach each other on a highway. One driver honks his horn, emitting a sound with a frequency of 400 Hz. If both cars are moving at a velocity of 27.0 m/sec, what pitch is heard by the other driver?
At rest, a car's horn sounds the note A (440 Hz). The horn is sounded while the car is moving down the street. A bicyclist moving in the same direction with one-ninth the car's speed hears a frequency of 416 Hz. (a) Is the cyclist ahead of or behind the car? e ahead of the car behind the car behind the car What is the speed of the c, r? (Assume the speed of sound in air is 343 m/s.)...
An ambulance driver traveling at 32.0 m/s (71.6 mph) honks his horn as he sees a motorist ahead on the highway traveling in the same direction. The motorist hears a frequency of 392 Hz and notices that his own speedometer reads 33.6 mph (15.0 m/s). Calculate the frequency that the ambulance driver hears. (Speed of sound is 340 m/s) (in Hz)
