For example, suppose the upper plate is positive, and the lower plate is negative, then the direction of the electric field is given as shown below figure. Webb23 juni 2024 · Sorted by: 4. An electromagnetic wave can oscillate in any direction perpendicular to the direction of the wave propagation. This direction of oscillation is called the polarization of the wave. In your example, the wave is moving in the z direction, so it can oscillate in any direction in the x − y plane. If the wave was polarized in the y ...

WebbBecause an electric field has both magnitude and direction, the direction of the force on a positive charge is chosen arbitrarily as the direction of the electric field. Because positive charges repel each other, the electric field around an isolated positive charge is oriented radially outward. WebbAn electric dipole in an external electric field is subjected to a torque τ = pE sin θ, where θ is the angle between p and E. The torque tends to align the dipole moment p in the direction of E. The potential energy of the dipole is given by Ue = − pE cos θ, or in vector notation Ue = − p · E. In a nonuniform electric field, the ...
