the sound intensity is measured in work /m .that means , si unit of sound intensity is decibel ( db) .
In the SI the unit of luminous intensity is candela(cd).
Intensity is measured in Candela. Candela is its SI unit.
The SI unit of color intensity is candela per square meter (cd/m^2).
The SI unit for the amplitude of sound is decibel. It is written as dB.
The SI unit of loudness is the decibel (dB), which is a logarithmic unit that quantifies sound levels relative to a reference level. Loudness itself, as perceived by the human ear, is not measured directly in SI units but is often represented in terms of decibels. In acoustics, sound pressure level (SPL) is also commonly used to express sound intensity in decibels, with a reference level typically set at 20 micropascals.
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.
Light intensity is also known as luminosity. Candela is the si unit
In the SI the unit of luminous intensity is candela(cd).
The SI unit of Intensity of light is CANDELA.
Intensity is measured in Candela. Candela is its SI unit.
The unit of sound intensity measurement is the decibel (dB).
The SI unit of color intensity is candela per square meter (cd/m^2).
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".
This unit is W/m2.
The SI unit of luminous intensity is the candela.
The SI unit for luminous intensity is candela (cd).
The SI unit for the amplitude of sound is decibel. It is written as dB.
