Light intensity is also known as luminosity. Candela is the si unit
The SI unit of luminous intensity is the candela.
Candela is the SI base unit for luminous intensity, and its symbol is cd. The ounce is not an SI unit, but it is commonly used for mass and not interchangeable with SI units. Newton is the SI base unit for force, and its symbol is N.
The SI unit of sound is the decibel (dB), which measures sound intensity. In the CGS system, the unit of sound is the bel (B), where 1 bel is equivalent to 10 decibels.
The light intensity formula is I P/A, where I is the intensity of light, P is the power of the light source, and A is the area over which the light is spread. This formula can be used to measure the brightness of a light source by calculating the intensity of the light emitted per unit area. The higher the intensity value, the brighter the light source is perceived to be.
The brightness of light is determined by the intensity of the light source, which is the amount of light energy emitted per unit of time. The greater the intensity of the light source, the brighter the light will appear.
The SI unit of Intensity of light is CANDELA.
The SI unit for luminous intensity is candela (cd).
The SI unit of luminous intensity is the candela.
In the SI the unit of luminous intensity is candela(cd).
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".
Intensity is measured in Candela. Candela is its SI unit.
A lux (lx) is the SI unit of iluminance, or light intensity as seen by the human eye.
The SI unit of color intensity is candela per square meter (cd/m^2).
This unit is W/m2.
the sound intensity is measured in work /m .that means , si unit of sound intensity is decibel ( db) .
If you think to an electrical current the SI unit is ampere (A).
Luxmeter measures luminous intensity. The SI unit of luminous intensity is candela (cd).
