A speaker is generating waves in a gas that is closed in a tube. The tubes closed end is at x=0 and the speaker is at x=1. The motion of the membrane is given by
[tex]s=s_0 \cdot sin(\omega t)[/tex]
How does the particle displacement vary with x and t? The wavelength is [tex]\lambda[/tex]I do not know how to solve it. But i thougt of expressing it like this:
[tex]s_1=s_0 sin(kx + \omega t)[/tex] (wave due to speaker oscillation, traveling from x=1 to x=0)
[tex]s_2=s_0sin(kx - \omega t)[/tex] (reflected wave at x=0 traveling to x=1)
The problem is that the reflected wave is reflected again and again...
