Amplitude of Wave

  1. Mar 24, 2008 #1
    For the wave shown in this drawing, what is the amplitude at x = 6 cm?
    [Hint: Remember that the wave will be moving. So even though there presently is an node at x = 6 cm, this will change at a later time.]

    I put 0 cm as the answer but I got it wrong and I don't understand why it's not zero. Could someone please help me?

    I think you need to understand the difference between the amplitude and the instantaneous displacement of the particle.
