Web(4), the solid angle is dimensionless. However, to aid in communication, it has been given the unit steradian, abbreviated sr. Since the area of a sphere is 4π times the square of its radius, for a unit radius sphere the area is 4π and the solid angle subtended by it is 4π sr. The solid angle subtended by a hemisphere is 2π sr.

WebThis function represents the emitted power per unit area of emitting surface, per unit solid angle, and per unit frequency. Sometimes, Planck's law is written as an expression u(\nu,T) = \pi I(\nu,T) for emitted power integrated over all solid angles.
