. Wave Equation question

  1. Nov 12, 2007 #1
    URGENT. Wave Equation question

    I have a standing wave and it's various parameters. I need to work out the amplitude at a point 3 cm to the right of an antinode.

    I'm stumped as to how to approach it.

    A pointer in the right direction would be great!!!

    Can you post the actual question? What's the equation for describing a standing wave?
