The culmination of this theory, called electrodynamics, was the realization that light is nothing but a rapidly alternating electromagnetic field traveling through space in the form of waves. Today we know that radio waves, light waves, or X-rays are all electromagnetic waves, oscillating electric and magnetic fields differing only in the frequency

Light is a funny thing. Its wavelength defines what it can and can’t interact with. Anything smaller than the wavelength is functionally nonexistent to that photon. That’s why there’s a mesh over the window of a microwave. The holes in the mesh are too small for microwaves to pass through. But visible light, with a much shorter wavelength, can go

the wave equation produced results that said that waves actually live in three dimensions—that is, they are particle-like—and these particles could jump between quantum states of energy.
