Figure shows a plot of the transverse displacement of the particle of a string at `t = 0` through which a travelling wave is passing in the positive in the positive x-direction. The wave speed is `20cm//s`. Find  (a) the amplitude (b) the wavelength (c) the wave number and (d) the frequency of the wave.
