Consider each of the electric- and magnetic-field orientations. What is the direction of propagation of the wave if E*-Ei^,B=Bj^E=Ei^, B-=-Bj^. Express the direction of the propagation vector, PP-P_vec, 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. What is the direction of propagation of the wave if E=Ej^,B=Bi^E=Ej^,B=Bi^. Express the direction of the propagation vector, P*PP_vec, 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. What is the direction of propagation of the wave if E*=-Ek^,B=-Bi^E-=-EK^,B=-B^. Express the direction of the propagation vector, PP-P_vec, 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. What is the direction of propagation of the wave if E=Ei^,B=-Bk^E-Ei^,B=Bk^. Express the direction of the propagation vector, P*PP_vec, 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.
