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 ?
