The Science Of Light.
Hey, what's up? ArteTuga here. No... No one said "let there be light"... that's all you'll ever learn from religion, if it weren't for science we wouldn't know this: light like everything else is a consequence of the Big Bang.
Light is electromagnetic radiation, particularly radiation of a wavelength that is visible to the human eye (about 400700 nm, or perhaps 380750 nm[1]). In physics, the term light sometimes refers to electromagnetic radiation of any wavelength, whether visible or not.[2][3]
Four primary properties of light are: * Intensity * Frequency or wavelength * Polarization * Phase
Light, which exists in tiny "packets" called photons, exhibits properties of both waves and particles. This property is referred to as the waveparticle duality. The study of light, known as optics, is an important research area in modern physics.
The speed of light in a vacuum is presently defined to be exactly 299,792,458 m/s (approximately 186,282 miles per second). This definition of the speed of light means that the metre is now defined in terms of the speed of light. Light always travels at a constant speed, even between particles of a substance through which it is shining. Photons excite the adjoining particles that in turn transfer the energy to the neighbor. This may appear to slow the beam down through its trajectory in realtime. The time lost between entry and exit accounts to the displacement of energy through the substance between each particle that is excited.
Generally, EM radiation (the designation 'radiation' excludes static electric and magnetic and near fields) is classified by wavelength into radio, microwave, infrared, the visible region we perceive as light, ultraviolet, X-rays and gamma rays.
