Hi, I am having problems with the following question:
If the Sun subtends a solid angle Ω on the sky, and the flux from the Sun just above the Earth’s atmosphere, integrated over all wavelengths, is f(d_sun), show that the flux at the Solar photosphere is ∏f(d_sun)/Ω.
Does anybody have an idea on how to start? I thought following formulas could be useful:
Ω = A/d^2
L = f * 4 ∏ * d^2
I would truly appreciate some help!
