The notes produced by a bassoon range in frequency from approximately 55 Hz to 575 Hz. Find the possible range of wavelengths in air produced by the instrument when the speed of sound in air is 343 m/s. Anthony sends a series of pulses of amplitude 27 cm down a string that is attached to a post at one end. Assume the pulses are reflected with no loss of amplitude.(a) What is the amplitude at a point where two pulses are crossing if the string is rigidly attached to the post?1 cm(b) What is the amplitude at a point where two pulses are crossing if the end at which reflection occurs is free to slide up and down?
