Figure (15-E2) shows a plot of the transverse displacements of the particles of a string at t = 0 through which a travelling wave is passing in the positive x -direction. The wave speed is 20 cm s − 1 . Find (A) the amplitude, (B) the wavelength, (C) the wave number and (D) the frequency of the wave.
