What is the unit of luminious intensity?
candela--------------------------------------------The official international definition of candela (1979) is:"The candela is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 x 10e12 hertz and that has a radiant intensity in that direction of 1/683 watt per steradian".
Basic mks unit of light intensity is?
The SI unit of luminous intensity (luminosity) is thecandela (CD).illuminance: pH = phot = CD·sr·cm-2 (= 104 lx)luminance: L = Lambert = CD·cm-2 (= 104 lx)luminous emission: sb = stilb = CD·cm-2 (= 104 CD·m-2)quantity of light: lumerg = CD·sr·s (= 1 lm·s)
When a lamp is turned off is it luminous or non-luminous?
If the bulb is switched off, then we would call it non-luminous.
Is a lamp luminous or non luminous?
Planets( Mercury, Venus, Earth, Jupiter, Saturn, Uranus, Neptune) and also Moons are Non-Luminous objects they don't emit light. The reason we see them because they reflect light from the Sun.
What is the symbol for luminous intensity and how is it measured in the field of optics?
The symbol for luminous intensity is Iv, and it is measured in candelas (cd) in the field of optics.
What is symbol for candela?
The symbol of candela is cd. The luminous intensity or candlepower of a light is expressed in candelas.

What does the metric symbol candela stand for?
Candela (symbol: cd) represents luminosity, the intensity of emitted light. It's not a metric symbol, but a photometric symbol.
What is the luminous intensity standard?
candela
What is the Si of luminous intensity?
The SI unit of Intensity of light is CANDELA.
What is the symbol for candela?
A candela is the power emitted by a source of light in a set direction with a correction to account for the different sensitivity of the human eye to different wavelengths of light. One candela is defined as the luminous intensity of a light source emitting light in one direction at a frequency of 540 x 1012 hertz and has a radiant intensity in that direction of 1/683 watts per steradian.
What is the unit used to measure luminous intensity in the SI system?
The SI unit of luminous intensity is the candela.
