A transverse harmonic wave on a string is decribed by  `y(x,t) = 3.0 sin (36 t + 0.018x + pi//4)`  Where `x` and `y` are in `cm` and `t` in `s`. The positive direction of `x` is from left to right.  (a) Is this a travelling wave or a stationary wave ? If it is travelling, what are the speed and direction of its propagation ?  (b) What are its amplitude and frequency ?  (c) What is the initial phase at the starting point ?  What is the least distance between two successive crests in the wave ?
