Transverse Velocity
uy(x,t) = ? y/? t = “partial derivative with respect to t”
“derivative of y with respect to ‘t’ keeping ‘x’ fixed”
maximum transverse speed is ym ?
A more general form is y(x,t)=ym sin( kx- ?t-?)
(kx- ?t-?) is the phase of the wave
two waves with the same phase or phases differing by 2?n are said to be “in phase”
