What is the unit used to measure luminous intensity in the SI system?
The SI unit of luminous intensity is the candela.
Candela Ounce Newton SI base unit?
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.
What is the SI and CGS unit of sound?
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.
What determines the brightness of light?
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.
What is the light intensity formula and how can it be used to measure the brightness of a light source?
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.
What is the Si of luminous intensity?
The SI unit of Intensity of light is CANDELA.
The measure of intensity in LIGHT?
The SI unit for luminous intensity is candela (cd).
What is the unit used to measure luminous intensity in the SI system?
The SI unit of luminous intensity is the candela.
What is Si unit of luminous intensity?
In the SI the unit of luminous intensity is candela(cd).
What is the unit of luminious intensity?
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".
What is te SI base unit for luinous intensity?
Intensity is measured in Candela. Candela is its SI unit.
What is a lux a measure of?
A lux (lx) is the SI unit of iluminance, or light intensity as seen by the human eye.
What is the si unit of colour intensity?
The SI unit of color intensity is candela per square meter (cd/m^2).
What SI unit of intensity of sounds is?
This unit is W/m2.
What is the si unit of sound intensity?
the sound intensity is measured in work /m .that means , si unit of sound intensity is decibel ( db) .
What is a candela?
The candela is the SI unit of luminous intensity, representing the brightness of a light source in a particular direction. It is defined as the intensity of light emitted by a source that radiates monochromatic light of frequency 540 terahertz and has a radiant intensity of 1/683 watt per steradian. The candela is one of the seven base units in the International System of Units (SI) and is crucial for measuring light and illumination in various applications.
How intensity measured?
If you think to an electrical current the SI unit is ampere (A).
