Black is the color of objects that do not emit or reflect light in any part of the visible spectrum; they absorb all such frequencies of light. Evil, in many cultures is used to describe acts or thoughts which are contrary to some particular religion Luck (also called fortunity) is a chance happening, or that which happens beyond a person's control. In the sociological field, crime is the breach of a rule or Law for which some governing authority or force may ultimately prescribe a Punishment Silence is a relative or total lack of audible Sound you can not hear a thing it is quiet Elegance is the attribute of being unusually effective and simple Capital punishment, the death penalty or execution, is the Killing of a person by judicial process as Punishment. Chaos (derived from the Ancient Greek, Chaos) typically refers to Unpredictability, and is the antithesis of Cosmos.

Light, or visible light, is Electromagnetic radiation of a Wavelength that is visible to the Human eye (about 400–700 Sometimes black is described as an "achromatic color", but in practice it can be considered a color, as in expressions like "black cat" or "black paint".

Black can be defined as the visual impression experienced in directions from which no visible light reaches the eye. (This makes a contrast with whiteness, the impression of any combination of colors of light that equally stimulates all three types of color-sensitive visual receptors. White is a Color, the perception which is evoked by Light that stimulates all three types of color sensitive Cone cells in the Human eye Light, or visible light, is Electromagnetic radiation of a Wavelength that is visible to the Human eye (about 400–700 )

Pigments that absorb light rather than reflect it back to the eye "look black". A black pigment can, however, result from a combination of several pigments that collectively absorb all colors. If appropriate proportions of three primary pigments are mixed, the result reflects so little light as to be called "black".

This provides two superficially opposite but actually complementary descriptions of black. Black is the lack of all colors of light, or an exhaustive combination of multiple colors of pigment. See also Primary colors

In elementary science, far Ultraviolet light is called "black light" because, unseen (per se), it causes many minerals and other substances to fluoresce. Phosphorescence is a specific type of Photoluminescence related to fluorescence.

On January 16, 2008, researchers from Troy, New York’s Rensselaer Polytechnic Institute announced the creation of the darkest material on the planet. Troy is a City in New York, US, and the County seat of Rensselaer County. Rensselaer Polytechnic Institute, or RPI, is a Nonsectarian private Research University located in Troy, New York The material, which reflects only . 045 percent of light, was created from carbon nanotubes stood on end. See also Graphene, Buckypaper Carbon nanotubes (CNTs are Allotropes of carbon with a nanostructure that can have a length-to-diameter It absorbs nearly 30 times more light than the current standard for blackness, and is 3 times darker than the current record holder for darkest substance. Scientists claim that the new material has great potential in the manufacturing of solar panels. Solar panels are used to gather Solar energy from The sun. Solar panels help maintain a clean and sustainable environment using solar panels to gather the sunlight is [1]

Absorption of light

In keeping with the law of conservation of energy, as a black color surface absorbs the light particles that hit it, the surface's particles are getting excited (excited particles = higher temperature). In Physics, the law of conservation of energy states that the total amount of Energy in an isolated system remains constant and cannot be created although it may Light, or visible light, is Electromagnetic radiation of a Wavelength that is visible to the Human eye (about 400–700 Temperature is a physical property of a system that underlies the common notions of hot and cold something that is hotter generally has the greater temperature The color black attracts heat and absorbs it making the object that is black warmer, because the particles have warmed up and are moving faster.

Some of these can be seen as positive or negative, depending on one's stance. For example, superstitions related to black cats hold them to be bad luck in the U.

Negative symbolism

Black can also carry negative connotations. The reasons for this are various, but the most widely accepted explanations are that night is perceived as dangerous. Night or nighttime is the period of Time when the Sun is below the Horizon. Especially before electric lights, darkness was potentially threatening. A secondary reason is that stains are most visible as dark additions to pale materials. Some people associate black with evil and destruction as it naturally absorbs all light and even the Black Hole is described as 'nature's ultimate fury'.

This use of the word and its associations carries over from night and objects to people as well. In traditional class-based Western cultures, pale skin indicated genteel domestic or intellectual indoor-work as opposed to rough outdoor labor in the fields. Aspects of this black/white opposition are not unique to the West, as, for example in the Indian varna system and in Japanese geisha makeup. India, officially the Republic of India (भारत गणराज्य inc-Latn Bhārat Gaṇarājya; see also other Indian languages) is a country Varna (sa वर्ण varṇa) is a Sanskrit term derived from the root meaning "to enclose" or are traditional female Japanese Entertainers whose skills include performing various Japanese arts such as classical music and dance African, Afro-Caribbean and African-American writers, such as Frantz Fanon, Langston Hughes, Maya Angelou, and Ralph Ellison, identify a number of negative symbolisms surrounding the word "black", arguing that the good vs. African Americans or Black Americans are citizens or residents of the United States who have origins in any of the black populations of Africa Frantz Fanon ( July 20, 1925 – December 6, 1961) was a Psychiatrist, philosopher, revolutionary and author from Langston Hughes (February 1 1902 &ndash May 22 1967 was an American Poet, Novelist Playwright, Short story writer and Columnist Maya Angelou (ˈmaɪə ˈændʒəloʊ (born Marguerite Ann Johnson on April 4, 1928) is an American Poet, Memoirist Ralph Waldo Ellison ( March 1, 1914 &ndash April 16, 1994) was a Scholar and Writer. bad dualism associated with white and black provide prejudiced connotations to color terminology for race. In most societies and by some anthropologists color terminology was used to label races sometimes in addition to a non-color term for the same race.
