Homework Help: Wave problem in Physics

  1. May 18, 2004 #1
    From the figure, please see the attachment. Which particles vibrate in phase with particle b and why?
    Can I say that particle c and d vibrate in phase with particle b?

    Another question: What is the function of the spongy lining at the edges of ripple tank when we generate water wave in the ripple tank?

    Assuming that you mean you picture to represent a wave with the two endpoints fixed, then d is in phase with b (they will always be at the same height). c is not.

    As for the spongy lining, it is there to absorb the wave so you won't have reflections confusing the situation.
