If an electromagnetic wave has components E_y = E₀ sin(kx

Question

If an electromagnetic wave has components E_y = E₀ sin(kx - ωt) and B_z = B₀ sin(kx - ωt), in what direction is it traveling? A) -x B) +x C) +y D) -y E) +z

Quizplus · Accepted Answer

The direction of propagation of an electromagnetic wave is given by the direction of the electric and magnetic fields. In this case, the electric field is in the y direction and the magnetic field is in the z direction. The wave is propagating in the x direction since both the electric and magnetic fields are perpendicular to the direction of propagation. Therefore, the answer is choice B, +x.
