i got your answer.thanks a lot!
i never accounted for gravity also pulling down the string even further.
but then shouldn't the amplitudes be different ?
I mean we use the formula y=2Asin(wt)cos(kx), where the amplitude on either sides is the same.
is this an approximation of some sort?
hi, i had this doubt regarding stationary waves
consider a string held between two points and vibrating in fundamental mode, so that there will be nodes at the fixed points.
then consider the datum of the potential energy at the mean position.
now when all particles have gone up by their...
