A student doing a speed-of-sound lab on a closed-open system hears a resonance with a tuning fork when the pvc pipe extends exactly 0.253 m out of the water. Using the same tuning fork, they do not hear another resonance until the pipe is exactly 0.421 m out of the water. If the temperature of the room is 23°C, what is the frequency of the tuning fork?

After years of being alone and never getting a single phone call, Daniel understandably forgets to shut off his cell phone in class. One miraculous day, he finally receives a call and accidentally allows the ringer to emit sound waves uniformly in all directions. At a distance of 13.0 m. from the source, Mr. O''Hara's sensitive ears observe the intensity level to be 94.0 dB. What is the total acoustic power output of the cell phone speaker, in watts?
You have an open-open pipe of adjustable length near a taut 60.0 cm, 5.0 gram guitar string which is under a tension of 300 N. You want to adjust the length of the tube so that when it produces a sound in its fundamental frequency, this sound is at the same frequency of the string’s vibration in its second harmonic. What should be the length of the pipe?
Two trumpets are being tuned using beats. One has a frequency of 440 Hz. When the second is played along with it, 15 beats are heard in 5.0 s. What are the possible frequencies of the second trumpet?
An organ pipe is open at both ends. It is producing sound at its n = 3 harmonic, the frequency of which is 164 Hz. Take the speed of sound to be 345 m/s. What is the length of the pipe?
A turning fork is held over a resonance tube, and resonance occurs when the surface of the water is 12 cm below the top of the tube. Resonance occurs again when the water is 34 cm below the top of the tube. If the air temperature is 23 , find the frequency of the turning fork.
