Homework Help: Wave Problem

  1. May 8, 2010 #1
    I am stuck on a question about standing waves:

    'The diagram below show's Melde's experiment and demonstartion of a stationary wave on a string'

    The string has 3 full wavelengths shown, and 3 points are marked:

    Point A is on an antinode, Point B is on the same antinode, but very fractionally to the right, and point C is on an antinode out of phase (see the attachment for a similar diagram) - A is in red, B is in black, C is in blue

    The first question is easy:
    "State whether the following paris of points on the string are in phase, in antiphase, or neither in phase nor antiphase

    A and B - I put that they are both in phase
    A and C - I put that they are in antiphase

    The next question (the tough nut):
    "Describe briefly how you could check this experimentally"

    I have no idea!

    Any form of help/guidance will be much appreciated
