A sphere of radius R, at a distance r from the observer, has a uniform brightness B. The specific intensity is equal to B if the ray intersects the sphere, and zero otherwise. Use equation (3.41) to express the flux ℱ in terms of brightness B and , the angle at which a ray from the observer is tangent to the sphere (i.e., 2 is the angle subtended by the sphere as seen from the observer). Show that on the surface of the sphere, ℱ=πB (eq. 3.7). | Numerade
