Since the electric field in this case oscillates along the x-axis, the electromagnetic wave is said to be ...
WebThe electric field is defined mathematically as a vector field that can be associated with each point in space, the force per unit charge exerted on a positive test charge at rest at that point. The electric field is generated … WebThe electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge. Suggest Corrections. 11.
