Question

what is luminous intensity​

Answer 1

• In photometry, luminous intensity is a measure of the wavelength-weighted power emitted by a light source in a particular direction per unit solid angle, based on the luminosity function, a standardized model of the sensitivity of the human eye. The SI unit of luminous intensity is the candela, an SI base unit.

Answer 2

Answer:

Explanation:

Luminous intensity, the quantity of visible light that is emitted in unit time per unit solid angle. The unit for the quantity of light flowing from a source in any one second (the luminous power, or luminous flux) is called the lumen.

The luminous intensity is a quantity for characterizing a light source. It is defined as the luminous flux per unit solid angle. ... The SI units of the luminous intensity are the candela = lumen per steradian (cd = lm/sr). One candela approximately corresponds to the luminous intensity of a normal candle.
