Consider each of the electric- and magnetic-field orientations given next. In each case, what is the direction? Consider each of the electric- and magnetic-field orientations given next. In each case, what is the direction of propagation of the wave? 1) E in the +Xdirection, B in the +Y direction. 2) E in the -y direction, B in the +x direction. 3)E in the +y direction, B in the -z direction. answer choices are : +y -y +z -z +x -x
