Hi Tyserius,
You seem really smart :D
What was the answer to what could be deduced about the formation of the stationary waves by the speed or something?
It was in the same question.
Thanks mate, cheers.

Lol, I'm not that. Well, the answer is :
A wave is incident from the oscillator and travels towards the other end P and then reflected back towards the oscillator. The oscillator would also be causing more waves. As the two waves travel in opposite directions, they happen to experience superposition and form a stationary wave. The speed calculated is the speed of the incident wave or the reflected wave.

Dang. I wish I didn't re-take Physics. I was trying to get a higher score and I think I'll end up with a far lower one and I've wasted a few poundsterling for it.
