A Harmonic Wave Travels In The Positive X Direction. Try to follow some point on the wave, for example a crest. A fixed point on the string oscillates as a function of time according to the equation y = 0.0085 cos(2t)where y is the displacement in meters and the time t is in seconds.

Problem 33 a sine wave is traveling to the right on a cord. Ψ(x,t) = asin(kx−ωt+ ), (15) where is the initial phase. Find the (a) amplitude, (b) wavelength, (c) period, and (d) speed of the wave.

Think of a water w. A harmonic wave travels in the positive x direction at 12 m/s along a taught string. Hence the velocity of the particles at d is cos(3π/2)=0. If c =90° (= π/2 radians), then y is a maximum amplitude (a in our case).
