Two pipes, equal in length, are each open at one end. Each has a fundamental frequency of 479 Hz at 18 C. In one pipe the air temperature is increased to 21 C. If the two pipes are sounded together, what beat frequency results?© BrainMass Inc. brainmass.com February 24, 2021, 2:11 pm ad1c9bdddf
Frequency is given by
f = velocity / wavelength
velocity of sound is dependent on temperature. It is given by
v = 331+0.6T .
Let V1 = ...
The solution defines the problem and works through to the answer.
