★There are natural light sources such as sun, fireflies, lightning and aurora, or man-made artificial light sources such as oil lamps, lamp, laser, CRT, light emitting diodes.

★The main source of light on Earth is the sun (sunlight). Artificial light sources include incandescent, fluorescent lamps, LEDs, lasers and chemical light. In general we can distinguish between thermal light generated due to high temperature and approximately has a Planck spectrum, and light from quantum transitions, which has one line or band spectrum.

Of the above-mentioned radiation sources are only the sun and the light bulb thermal light sources. The reduced spectrum of fluorescent lamps is substantially responsible for ensuring that colors of objects in their light is often perceived as "unnatural". LEDs and lasers deliver approximately monochromatic light, ie light of only one frequency.

★The transitions between colors are flowing, the personal impression of color individually nameable countable color is subjective and by language, tradition and thinking conditionally. In different languages (originally) occurring words for colors.

★Light in the society

Light, like fire, one of the most important phenomena for all cultures. Artificially generated light from lamps enables the people today have a pleasant and safe living in terrestrial and darkness (night) and in closed spaces (caves, buildings).

Technically, the function group, the light is produced, known as lamp or bulb. The holder for the lamp is a lamp with this. "Light" and "light" .

In Christianity, the light in the self-designation of Jesus Christ is the salvation of man from the darkness of the distance from God. In the biblical story of creation is the light of the first work of God.

Hindu and Buddhist theoriesIn ancient India, the Hindu schools of Samkhya and Vaisheshika, from around the 6th–5th century BC, developed theories on light. According to the Samkhya school, light is one of the five fundamental "subtle" elements (tanmatra) out of which emerge the gross elements. The atomicity of these elements is not specifically mentioned and it appears that they were actually taken to be continuous.

The Indian Buddhists, such as Dignāga in the 5th century and Dharmakirti in the 7th century, developed a type of atomism that is a philosophy about reality being composed of atomic entities that are momentary flashes of light or energy. They viewed light as being an atomic entity equivalent to energy, similar to the modern concept of photons, though they also viewed all matter as being composed of these light/energy particles.

It is written in the Rigveda that light consists of three primary colors. "Mixing the three colours, ye have produced all the objects of sight!"

★The special theory of relativity

Albert Einstein had proposed the Theory of relativity.The wave theory was wildly successful in explaining nearly all optical and electromagnetic phenomena, and was a great triumph of nineteenth century physics. By the late nineteenth century, however, a handful of experimental anomalies remained that could not be explained by or were in direct conflict with the wave theory.

One of these anomalies involved a controversy over the speed of light. The constant speed of light predicted by Maxwell's equations and confirmed by the Michelson-Morley experiment contradicted the mechanical laws of motion that had been unchallenged since the time of Galileo, which stated that all speeds were relative to the speed of the observer. In 1905, Albert Einstein resolved this paradox by revising the Galilean model of space and time to account for the constancy of the speed of light.

Einstein formulated his ideas in his special theory of relativity, which advanced humankind's understanding of space and time. Einstein also demonstrated a previously unknown fundamental equivalence between energy and mass with his famous equation

where E is energy, m is, depending on the context, the rest mass or the relativistic mass, and c is the speed of light in a vacuum.

★Quantum theory

A third anomaly that arose in the late 19th century involved a contradiction between the wave theory of light and measurements of the electromagnetic spectrum emitted by thermal radiators, or so-called black bodies.

Physicists struggled with this problem, which later became known as the ultraviolet catastrophe, unsuccessfully for many years. In 1900, Max Planck developed a new theory of black-body radiation that explained the observed spectrum.

Planck's theory was based on the idea that black bodies emit light (and other electromagnetic radiation) only as discrete bundles or packets of energy. These packets were called quanta, and the particle of light was given the name photon, to correspond with other particles. being described around this time, such as the electron and proton.

A photon has an energy, E, proportional to its frequency, f, by where h is Planck's constant, λ is the wavelength and c is the speed of light. Likewise, the momentum p of a photon is also proportional to its frequency and inversely proportional to its wavelength:

As it originally stood, this theory did not explain the simultaneous wave- and particle-like natures of light, though Planck would later work on theories that did. In 1918, Planck received the Nobel Prize in Physics for his part in the founding of quantum theory.

★Speed of light

Presently, the speed of light in a vacuum is defined to be exactly 299,792,458 m/s (approximately 186,282 miles per second). The fixed value of the speed of light in SI units results from the fact that the metre is now defined in terms of the speed of light.
