Question

A standing sound wave experiment is set up in thelaboratory. A 1.0 m vertical glass tube is filled to the 25 cmmark with water. Near the open end is a loudspeaker that isdriven by an audio oscillator whose frequency can be varied from 10to 500 Hz. Assume the speed of sound in air is 343 m/s. A. What is the lowest frequency of the oscillator that willproduce resonance in the tube? B. What is the highest frequency that will produceresonance?

Explanation / Answer

A standing sound wave experiment is set up in thelaboratory. A 1.0 m vertical glass tube is filled to the 25 cmmark with water. Near the open end is a loudspeaker that isdriven by an audio oscillator whose frequency can be varied from 10to 500 Hz. Assume the speed of sound in air is 343 m/s. A. What is the lowest frequency of the oscillator that willproduce resonance in the tube?
lowest frequency=V/4l=343/4*0.75=114.33Hz
B. What is the highest frequency that will produceresonance?

next and highest frequency=3*114.33=343Hz
A. What is the lowest frequency of the oscillator that willproduce resonance in the tube?
lowest frequency=V/4l=343/4*0.75=114.33Hz
B. What is the highest frequency that will produceresonance?

next and highest frequency=3*114.33=343Hz
