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?
The wave is travelling.
The wave is travelling in the negative x-direction i.e. from right to left.
