I would appreciate help on this problem.
f = (1/2L)*sqrt(F/u)
This is vibrating at its fundamental frequency so L = (wavelength/2). To find k I reckon I need to find the force on the band and this should equal -kx. But I don't have the length of the string or the mass density. Is there a formula I am missing or something or what ?
Edit; or possibly it has something to do with this y = 2 Asin(kx+ot)sin(wt+ot). o is phase angle.
Thanks!
