I know that the SI unit of Intensity is W/m^2. I came across one more unit of intensity -> AU..but could not get much on that. Can anybody tell me the conversion formula ( from SI to AU ) ?
The conversion formula for intensity units from SI (International System of Units) to AU (arbitrary units) is: IAU = ISI x (1/λ)2, where IAU is the intensity in AU, ISI is the intensity in SI, and λ is the wavelength of light in meters.
Conversion between SI and AU intensity units is necessary because different fields of science and technology may use different units to measure intensity, which can lead to confusion and inaccuracies in data analysis. Converting to a common unit, such as AU, allows for easier comparison and communication of results.
To convert from SI to AU intensity units, simply plug in the value of the intensity in SI into the conversion formula: IAU = ISI x (1/λ)2. Make sure that the wavelength of light is also in SI units (meters). The resulting value will be the intensity in AU.
No, the conversion formula for intensity units from SI to AU is specifically for light intensity measurements. It is not applicable for other types of intensity measurements, such as sound or electric field intensity.
Yes, the conversion formula for intensity units from AU to SI is the inverse of the formula for SI to AU: ISI = IAU x λ2, where ISI is the intensity in SI, IAU is the intensity in AU, and λ is the wavelength of light in meters. Simply plug in the value of the intensity in AU and the corresponding wavelength of light in meters to get the intensity in SI units.
