An electromagnetic wave is transporting energy in the negative y direction. at one point and one instant the magnetic field is in the positive x direction. the electric field at that point and instant is a. positive y direction explain b. negative y direction c. positive z direction d. negative z direction e. negative x direction

D.negative z direction.

Explanation:

Hello,

In this case, electromagnetic waves are waves that result when vibrations between an electric field and a magnetic field are exhibited, it means they are composed by both oscillating magnetic and electric fields. In such a way, when the electromagnetic wave is moving across the x-direction, the associated magnetic field oscillates across the xz-plane and the corresponding electric field across the xy-plane.

In this manner, the referred electromagnetic wave is transferring energy across the negative y direction, in addition, the magnetic field turns out positive across the x direction. Considering the aforesaid reasons, one concludes that the electric field at that point and instant is in the negative z direction.

Best regards.
