Ответ:
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
