In the figure below, S is a small loudspeaker driven by an audio oscillator with a frequency that is varied from 1000 Hz to 2000 Hz, and D is a cylindrical pipe with two open ends and a length of 55.0 cm. The speed of sound in the air-filled pipe is 344 m/s.
(In the figure s is a little speaker next to the pipe D)
(a) At how many frequencies does the sound from the loudspeaker set up resonance in the pipe?
(b) What is the lowest frequency at which resonance occurs?
(c) What is the second lowest frequency at which resonance occurs?
