A tuning fork with a frequency of 440 Hz is held above a resonance tube partially filled with water. Assuming that the speed of sound in air is 342 m/s, for what three smallest heights of the air column will resonance occur? {hint: for resonance to occur, the frequency of the tuning fork must match that of the tube.}

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?

A cylinder is filled with water. When it is let out, we hear one harmonic at 79.5 cm and another at 132.5 cm. If the speed of sound is 345 m/s, determine the resonance frequency of the pipe

In the figure, S is a small loudspeaker driven by an audio oscillator and amplifier, adjustable in frequency from 1300 to 2400 Hz only. Tube D is a piece of cylindrical sheet-metal pipe 50.0 cm long and open at both ends. (a) If the speed of sound in air is 344 m/s at the existing temperature, at how many frequencies will a resonance occur in the pipe when the frequency emitted by the speaker is varied from 1300 Hz to 2400 Hz? (b) What is the lowest resonant frequency in the given interval? (a) Number Units (b) Number Units
