Annotations

definition: "Amount of energy, per unit frequency interval, passing through a unit area oriented normal to a direction n, into a unit solid angle, in a unit time. I(nu,r,n,t) where nu is a frequency, r is position of measurement, n is direction from r. For a surface A with normal an angle theta from n the energy passing dA in the dw solid angle is dE = I*dA*cos(theta)*dnu*dw*dt" (string)
