Given the wave function: y(x, t) = 5sin27(0.2x - 3t); (x = meters, t = sec.): what are the amplitude, frequency, wavelength, angular frequency and phase velocity of the wave? in which direction is it traveling? (note: this wave is not a light wave traveling in a vacuum so va = 3 x 108 is not valid)
