Homework Help: Orientation Question

  1. Jun 7, 2007 #1
    1. The problem statement, all variables and given/known data

    A 150MHz sinusoidal plane wave propagates in air at 30 degrees with respect to the +x-axis in the x-y plane. The E-Field is polarized parallel to the plane of incidence and has a magnitude of 2 V/m.

    3. The attempt at a solution

    My only question is about the orientation. I can't figure out how to draw the picture! Click on the image below to see what I have now. Is one of these orientations correct?

    there isn't anything given in the question to indicate that.

    but because of the normal way we choose to represent the angles (CCW starting from the +x axis) I would choose to fo 30 degrees N of E
