Problem: The lowest frequency in most humans' audible range is 20 Hz.a. What is the length of the shortest open-open tube needed to produce this frequency?L = ___ mb. What is the length of the shortest open-closed tube needed to produce this frequency?L = ___ m

FREE Expert Solution

a. For open-open tube, frequency is:

f=nv2L

 f1 = (1)(v)/2L = v/2L

Solving for L:

L = v/2f1
