تعريف a candela في الإنجليزية الإنجليزية القاموس.
- standard candle
- candela
- In the International System of Units, the base unit of luminous intensity; the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 × 1012 hertz and that has a radiant intensity in that direction of 1/683 watt per steradian. Symbol: cd
- candela
- The unit of measure indicating the luminous intensity (candlepower) of a light source in a specific direction; any given light source will have many different intensities, depending upon the direction considered
- candela
- Derived from candle and denoted by the symbol "cd", it is the basic SI unit of luminous intensity It is defined as the radiation intensity, in a perpendicular direction, of a surface of 1/600000 square meter of a black body at the temperature of freezing platinum under a pressure of 101325 newtons per square meter
- candela
- A unit of luminous intensity (strength) from a light source or a lighting system in a given direction
- candela
- -The standard unit for luminous intensity One candela is equal to one lumen per steradian
- candela
- {i} (Optics) unit for measuring the intensity of light
- candela
- the International System (SI) unit of luminous intensity One candela is one lumen per steradian
- candela
- The luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 * 1012 hertz and that has a radiant intensity in that direction of (1/683) watt per steradian (16th CGPM (1979), Resolution 3) The previous is an excerpt from WWW version of the National Institute of Standards and Technology: Physics Laboratory's International System of Units (SI) Also called candle
- candela
- (cd) Unit of luminous intensity (brightness) (an SI base unit)
- candela
- unit for luminous intensity as related to human eye spectral response
- candela
- SI (Standard International) unit of luminous intensity: the candela is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 x 1012 hertz and has a radiant intensity in that direction of 1/683 watt per steradian (16th General Conference of Weights and Measures, 1979)
- candela
- A unit of luminous intensity in a given direction, equal to one lumen per steradian
- candela
- Unit of luminous intensity One candela is one lumen per steradian Formerly called the candle
- candela
- In the International System of Units, the base unit of luminous intensity; the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 × 10[12] hertz and that has a radiant intensity in that direction of 1/683 watt per steradian. Symbol: cd
- candela
- Véase doble claro
- candela
- the basic unit of luminous intensity adopted under the Systeme International d'Unites; equal to 1/60 of the luminous intensity per square centimeter of a black body radiating at the temperature of 2,046 degrees Kelvin
- candela
- – a bright green wrapper also known as double claro Heating the leaves during the drying process creates this color
- candela
- A base unit of luminous intensity
- candela
- The international unit (SI) of luminous intensity The term has been retained from the early days of lighting when a standard candle of a fixed size and composition was used as a basis for evaluating the intensity of other light sources Sometimes the term "candle power" is used to describe the relative intensity of a source
- candela
- The unit of measure for the intensity of light at the source roughly equal to the amount of light in any direction from the flame of a candle
- candela
- A unit of light intensity The luminance of a light source is often expressed in candelas per square meter
- candela
- a unit of measure indicting the amount of intensity developed by an artifical light
- candela
- Unit of luminous intensity One candela equals one lumen per steradian
- candela
- The SI unit of luminous intensity (formerly called the candle) One candela equals one lumen per steradian-the luminous intensity, in a give direction, of a source that emits monochromatic radiation at a frequency of 540E12 hertz and of which the radiant intensity in that direction is 1/683 watts per steradian
