Question

In an electromagnetic wave, at an instant and at a particular position, the electric field is along the negative z-axis and magnetic field is along the positive x-axis. Then the direction of propagation of electromagnetic wave is:, positive z-axis, positive y-axis, at 45 ° angle from positive y -axis, negative y-axis
