    Wave Phases? Wtf???

    1. The problem statement, all variables and given/known data

    2. Relevant equations

    None

    3. The attempt at a solution

    I managed to do the first part, but not the second part regarding phases. I don't have a clue how to work the second part out. I know that an anti-node is maximum amplitude and a node is at minimum amplitude. But I don't have a clue how to work out phases, nor do I understand what phase means or why it is used.

    Welcome to Physics Forums.

    It may help to write out the general equation for oscillation at a fixed point:

    y = A cos(ωt - φ)​

    φ is the phase they are speaking of. The question is, essentially, does φ change as the point P moves from X to Y.
