Superposition concept

  1. Jan 29, 2009 #1
    I am having a hard time grasping this concept. More specifically, I am having a hard time finding the net displacement of two waves when they are overlapping. My book describes the net displacement of two waves as the point-by-point summation of the individual waves.

    the bold statement is where I am getting lost. I know summation is just the sum of all the points. But are they talking about points on the Wave? Points on the graph?

    I'm in physics 122(algebra based) the second half of physics. My teacher is using College Physics by Knight, Jones, Field. If anyone has the same book the diagram is on pg 515 Figure 16.3.

    Thanks!

    Edit: It is the 1e which is the only edition of that book...
