A simple, harmonic oscillator at the point x=0 generates a wave on a rope. The oscillator operates at a frequency of 40 Hz and with an amplitude of 3.00 cm. The rope has a linear mass density of 50.0 g/m and is stretched with a tension of 4.50 N.
Write the wave function y(x,t) for the wave moving in +x-direction. Assume that the oscillator has its maximum upward displacement at time t=0.
I know to write the wave function I use the equation y(x,t)=Acos(kx-wt)
where A=3, k=2pi/[tex]\lambda[/tex]=8pi, w=2pif=80pi
So I got the equation y(x,t)=3cos(8pi x-80pi t)
However when I put it in it says the equation is wrong
Can anyone help me in figuring out what I missed?
Thanks
