The general expression for an idealized uniform plane water wave propagating in the +x direction is
h(x,t) = Acos(wt - kx + phi) m
where h represents the height of water particles at the water surface above the unpurturbed or quiescent water surface level, A is the wave amplitude, w is the radian frequency, k is the wave number, and phi is a reference phase angle. If the wave amplitude is 3m, the wave frequency is 2 Hz, the phase velocity is 1m/s, and you are told that h(0,0) = 1m, find an explicit expression for h(x,t).
