A sinusoidal wave traveling in the positive x-direction has an amplitude of 15cm, a wavelength of 40cm, and a frequency of 8Hz. The vertical position of an element of the medium at t=0 and x=0 has a displacement of 15cm.

(a) Find the wavenumber and angular frequency (expressed in terms of ! ), period, initial phase, and speed of the wave.

(b) Write down the wave equation using the numbers you calculated at (a) and graph the wave.
