Q 1968556405.     A transverse harmonic wave on a string is
described by `y(x, t) = 3sin (36t + 0.018x +
`pi`/4)`, where x, y are in cm and t in sec. The
positive direction of x-axis is from left to
right.
(i) Is this a travelling or stationary wave?
If it is travelling, what are the speed and
direction of its propagation?
(ii) What are its amplitude and frequency?
(iii) What is the initial phase at the origin?
(iv) What is the least distance between two
successive crests in the wave?
