Homework Help: Electric field on EM wave

  1. Mar 22, 2010 #1
    1. The problem statement, all variables and given/known data

    There is an EM wave (http://www.geo.mtu.edu/rs/back/spectrum/) that has theoretical points all along the thick line that runs along both the electric/magnetic waves. What could you say about the electric field at these points?

    2. Relevant equations

    None

    3. The attempt at a solution

    My possible choices are that the E. fields are zero, have a constant value, or are proportional to the length of the B field arrows. I think the E fields will be 0 but I'm unsure why that would be the case.
