Okay so heres the question

How do I do this with an explanation please!
Also what if the question was a different and it wasn't a stationary wave... just your standard transverse wave and the point X was at say a different point how would I know what direction it would move?

Well I think the question is not so much about which direction it moves in, but how it moves. You know that X has amplitude and amplitude is directly proportional to intensity; as a result, it will vibrate with its equilibrium being the centre around which it vibrates.

It's a standing wave. So it is only going to move up and down.

If it was a travelling wave then the point would move along the line described by y=Acos(kx-wt+\phi)

If it were a transverse wave, as the wave moved say to the right, and the region of compression moved to the right, the point would move to the left.

good revision website for physics saved me a couple of times www.technocratnotes.com

and good revision apphttps://play.google.com/store/apps/d...s.app&hl=en_GB

can you add this to your originalpost please so that any new ppl to the thread see this. thanks

There is no "horizontal" displacement in a stationary wave, so point X or any other point on the wave would just move up and down.
