Question

A pipe that is open at both ends has a fundamental frequency of 320 Hz when the speed of sound in air is 334 m/s. What is the length of this pipe

Answer 1

Answer:

Length of pipe 0.5m

Explanation:

Step one

Given data

fundamental frequency of 320 Hz

n=1

Velocity v=334m/s

Note: the subsequent frequency of sound are a multiple of it fundamental frequency

Step two

Applying the formula we have

Fn=nv/2l

Substitute

320=1*334/2L

Cross multiply

320*2L=334

640L=334

Divide both sides by 640

L=334/640

L=0.5m
