Consider the waveform expression.

$y(x,t)=y_{m}sin(639t+2\mathrm{.}72+0\mathrm{.}197x)$

The transverse displacement $(y)$ of a wave is given as a function of position $(x$ in meters$)$ and time $(t$ in seconds$)$ by the expression. Determine the wavelength, frequency, period, and phase constant of this waveform.
