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? http://img299.imageshack.us/img299/4291/questionspicex7.th.jpg [Broken] Thanks!
