Consider each of the electric- and magnetic-field orientations

What is the direction of propagation of the wave if E = - Ek^, B  = - Bi^. Express the direction of the propagation vector, P, as a unit vector. Its three components should be entered in order (x,y,z) separated by commas. For example, if the wave propagates only in the -x direction, enter -1,0,0. <-- for all of them
