Compute the irradiance at a point due to a unit-radius disk h units directly above its normal with constant outgoing radiance of 10 W/m2 sr. Do the computation twice, once as an integral over solid angle and once as an integral over area. (Hint: If the results don’t match at first, see Section 13.6.2.)

Given Radiance L= 10W/m2Sr
We have disc shaped light source having unit radius. Distance between source and point is h directly above normal of disc
1. Integral over solid angle
E=
Here is angle between normal to disc and Vector to point p, d is distance between point p and dA
In our Case...
