- ##\phi=\frac{2\pi x}{\lambda}##
I answered A but the answer key is B.
I thought since the wave is moving to the right, P started first compared to Q (the crest of P is closer to y-axis compared to Q). Why is the correct answer B?
Thanks
Edit:
Wait, is it because the x-axis is position so the position of Q is in front of P (more to the right)?
If the x-axis is time, then P will lead Q since P starts earlier?
