A speaker is placed at the opening of a long horizontal tube. The speaker oscillates at a frequency of f creating a wave that moves down the tube. The wave moves through the tube at a speed of v=330 m/s. At time t= 0s an air molecule at x=1m is at the maximum displacement of 5 nm. At the same time another molecule at x=3.7m has a displacement of 3.5nm. What is the wave function of the sound?

Expert Solution

We know for a sound wave travelling through a medium , the wave function can be described by a cosine or sine function.

Where A is the amplitude of the wave.
