SI unit of luminous intensity is ______. (1) lumen (2) lux (3) candela (4) watt

1 Answer

Answer :

(3) candela Explanation: 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 (cd).
