A transverse harmonic wave on a strin 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 ?
