Solid_Angle,_1_Steradian.svg


Summary

Description
English: A solid angle is a three-dimensional analog of a circular angle that relates a portion of the volume of a sphere to the surface area it subtends. If that area equals the sphere’s radius squared, the solid angle is one steradian. This diagram displays two solid angles of one steradian, viewed from different directions.
