. A transverse harmonic wave on a string is described

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 origin?

(d) What is the least distance between two successive crests in the wave?

Best Answer


The equation of progressive wave travelling from right to left is given by the displacement function:-
