The SI unit, candela, was in fact based on an older unit called the " candlepower ", which represented the luminous intensity emitted by a candle made to particular specifications ( a " standard candle " ).
32.
He was the first to use the vacuum tube with the capillary part now called a Geissler tube, by means of which the luminous intensity of feeble electric discharges was raised sufficiently to allow of spectroscopic investigation.
33.
In 1881, Jules Violle proposed the " Violle " as a unit of luminous intensity, and it was notable as the first unit of light intensity that did not depend on the properties of a particular lamp.
34.
The characters in Craig Lucas'" Blue Window, " directed by Joe Mantello, are introduced with an image of luminous intensity : framed within an inky darkness, picked out by individual spotlights, seven faces stare at us from the stage.
35.
:Well, without some sort of protection, you would be blinded almost instantaneously by the luminous intensity, and your retinas will be permanently scarred by a combination of the full spectrum, including but not limited to gamma, x-ray, and ultraviolet.
36.
Each photographed color component, initially just a colorless record of the luminous intensities in the part of the spectrum that it captured, is processed to produce a transparent dye image in the color complementary to the color of the light that it recorded.
37.
In addition, Lambert postulated a surface that emits light ( either as a source or by reflection ) in a way such that the density of emitted light ( luminous intensity ) varies as the cosine of the angle measured from the surface perpendicular.
38.
The coefficient of luminous intensity, " R I ", is the measure of a reflector performance, which is defined as the ratio of the strength of the reflected light ( luminous intensity ) to the amount of light that falls on the reflector ( normal illuminance ).
39.
The coefficient of luminous intensity, " R I ", is the measure of a reflector performance, which is defined as the ratio of the strength of the reflected light ( luminous intensity ) to the amount of light that falls on the reflector ( normal illuminance ).
40.
The SI standard recommends the usage of the following dimensions and corresponding symbols : length ( L ), mass ( M ), time ( T ), electric current ( I ), absolute temperature ( ? ), amount of substance ( N ) and luminous intensity ( J ).
