Question

A length of organ pipe is closed at one end. If the speed of sound is 344 m/s, what length of pipe is needed to obtain a fundamental frequency of 63 hz?.

Answer 1

Answer:

Node-Antinode       for a pipe closed at one end (fundamental)

The length of such a pipe would be wavelength / 4

lambda (wavelength) = speed / frequency = 344 m/s / 63 / sec = 5.46 m

The pipe would have to be 5.46 / 4 = 1.36 m
