An extended source emits 2.00 W cm-2 sr-1 nm-1 at 300 nm. Calculate the spectral radiant power impingent on a 1.00 cm2 receptor that5 is 2.00 M away in W nm-1 and photons s-1 nm-1 if a 1.00 mm diameter aperture is placed at the source. What is the incident radiant power in watts over 10.0 nm centered at 300 nm if the source radiance is constant over this region?
