Radiation Intensity in Radiation Formulas

Radiation Intensity for emitted radiation is the rate at which radiation energy is emitted in a direction per unit area normal to this direction and per unit solid angle about this direction. And is denoted by I_e. Radiation Intensity is usually measured using the Watt per Square Meter Steradian for Radiance. Note that the value of Radiation Intensity is always positive.

FAQ

What is the Radiation Intensity?

Radiation Intensity for emitted radiation is the rate at which radiation energy is emitted in a direction per unit area normal to this direction and per unit solid angle about this direction. Radiation Intensity is usually measured using the Watt per Square Meter Steradian for Radiance. Note that the value of Radiation Intensity is always positive.

Can the Radiation Intensity be negative?

No, the Radiation Intensity, measured in Radiance cannot be negative.

What unit is used to measure Radiation Intensity?

Radiation Intensity is usually measured using the Watt per Square Meter Steradian[W/m²*sr] for Radiance. Watt per Square Meter Square Degree[W/m²*sr], Watt per Square Meter Spat[W/m²*sr] are the few other units in which Radiation Intensity can be measured.
