Re: Energy Transmission on a string.

Joel,

I think you are still missing the point.  The maximumn angle of a
*perfectly* sinusoidal traveling wave with a wavelength of 1 m and
an amplitude of 1 cm is less than 4 degrees.  And even this would
be an outrageously large angle for waves on a guitar string.
