Whois & Analysis for atierma.tk

A chandelier is a decorative ceiling-mounted light fixture, a distinct type of pendant light.

Chandeliers are often ornate, and normally use incandescent light bulbs, though some modern designs also use fluorescent lamps or even LEDs.

Crystal chandeliers have more or less complex arrays of crystal prisms to illuminate a room with refracted light.

Chandeliers are often located in hallways, living rooms, dining rooms, and recently in bathrooms and bedrooms.

Lighting or illumination is the deliberate use of light to achieve a practical or aesthetic effect.

Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight.

Daylighting (using windows, skylights, or light shelves) is sometimes used as the main source of light during daytime in buildings.

This can save energy in place of using artificial lighting, which represents a major component of energy consumption in buildings.

Proper lighting can enhance task performance, improve the appearance of an area, or have positive psychological effects on occupants.

Light is electromagnetic radiation within a certain portion of the electromagnetic spectrum.

The word usually refers to visible light, which is visible to the human eye and is responsible for the sense of sight.

Visible light is usually defined as having wavelengths in the range of 400–700 nanometres (nm), or 4.00 × 10−7 to 7.00 × 10−7 m, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths).

This wavelength means a frequency range of roughly 430–750 terahertz (THz).

Chromium is a chemical element with symbol Cr and atomic number 24.

It is the first element in Group 6.

It is a steely-grey, lustrous, hard and brittle metal which takes a high polish, resists tarnishing, and has a high melting point.

The name of the element is derived from the Greek word χρῶμα, chrōma, meaning color, because many of the compounds are intensely colored.
