A wave travelling along a strong is described by  `y(x,t)=0.005 sin (80.0x-3.0t)`  in which the numerical constants are in SI units `(0.005m, 80.0 rad m^(-1)` and `3.0 rad s^( -1))`. Calculate (a) the amplitude. (b) the wavelength (c) the period and frequency of the wave. Also , calculate the  displacement y of the wave at a distance `x=30.0` cm and time  t=20 s?
