A sinusoidal wave propagates along a string. In figure (a) and (b). ' \( y \) ' represents displacement of particle from the mean position. ' \( x \) ' \( \& \) ' \( t \) ' have usual meanings. Find :
P wavelength, frequency and speed of the wave.

W maximum velocity and maximum acceleration of the particles the magnitude of slope of the string at \( x=2 \) at \( t=4 \mathrm{sec} \).
