Problem Details

Consider each of the electric- and magnetic-field orientations.

Part A. 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, P⃗P→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.

Part B.  What is the direction of propagation of the wave if E⃗=Ej^,B⃗=Bi^E→=Ej^,B→=Bi^.

Express the direction of the propagation vector, P⃗P→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.

Part C. What is the direction of propagation of the wave if E⃗=−Ek^, B⃗=−Bi^ E→=−Ek^,B→=−Bi^.

Express the direction of the propagation vector, P⃗P→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.

Part D. What is the direction of propagation of the wave if E⃗=Ei^,B⃗=−Bk^E→=Ei^,B→=−Bk^.

Express the direction of the propagation vector, P⃗P→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.
