An electromagnetic wave having equation, E → = E 0 cos ( k z - ω t ) i ^ travels in vacuum along z -direction. A rectangular loop is to be kept such that at t = 0 , displacement current may flow through its area. Which of the following is the correct orientation?

Step-by-step solution

We know that electromagnetic waves have electric as well as magnetic vectors which are vibrating perpendicular to each other and these two vectors are also vibrating perpendicular to the direction of the motion. Here, the direction of displacement current is the same as the direction of motion of wave which is along i ^   [ x -axis ] . So, area vector should also be along i ^ , i.e., y z plane.
