WebJan 29, 2024 · Electromagnetic Radiation Definition. Electromagnetic radiation is self-sustaining energy with electric and magnetic field components. Electromagnetic radiation is commonly referred to as "light", EM, EMR, or electromagnetic waves. The waves propagate through a vacuum at the speed of light. The oscillations of the electric and … WebWell, if the electric field points to the right and this charge is negative, then the electric force has to point to the left. And the reason is if this force vector is leftward and we divide it by a negative sign, that's gonna take this force vector and turn it from left to right. That means the electric field would be pointing to the right.
