A light wave is a form of electromagnetic (EM) radiation that has a wavelength in the visible portion of the EM spectrum. It consists of energy and it travels at the speed of light. Because it can travel through a vacuum (where no molecules exist), we know that B and E are incorrect (there are no other atoms or molecules in a vacuum to interact with). Also, light waves do not contain electrons or subatomic particles, so A is incorrect.
We know that EM radiation consists of two different components, an electric component and a magnetic component. They exists as waves that are in perpendicular planes to one another. They also oscillate in phase with one another in the direction that the light wave is travelling. So this means that the best answer is D.
