(temporary colours, i know they're nasty)

Basic intro: Image Welcome to the light portal. Light is electromagnetic radiation with a wavelength which is visible to the eye. The study of light is called optics. The speed of light in a vacuum is 299,792,458m/s. Due to the wave-particle duality of matter, light simultaneously exhibits properties of both waves and particles. The elementary particle which defines light is a photon. Theories of light...

Need attention: Portal:Electromagnetism, Portal:Scientific method. Oh no, I'm turning into a portal junkie.
