Detailed explanation-1: -candela (cd), unit of luminous intensity in the International System of Units (SI), defined as the luminous intensity in a given direction of a source that emits monochromatic radiation of frequency 540 × 1012 hertz and has a radiant intensity in that same direction of 1/683 watt per steradian (unit solid angle).
Detailed explanation-2: -The SI unit of luminous intensity is candela.
Detailed explanation-3: -The candela is the SI unit of luminous intensity. The candela is used to measure the visual intensity of light sources, like light bulbs or the bulbs in torches.
Detailed explanation-4: -The candela (/kænˈdɛlə/ or /kænˈdiːlə/; symbol: cd) is the unit of luminous intensity in the International System of Units (SI). It measures luminous power per unit solid angle emitted by a light source in a particular direction.
Detailed explanation-5: -The SI unit of luminous intensity is Candela and temperature is Kelvin.
