1a.If the sun subtends a solid angle (omega) on the sky, and the flux from the Sun just above the Earth's atmosphere, integrated over all wavelengths, is F(d) show that the flux at the solar photosphere is ((pi)F(d))/(omega)

B.The angular diameter of the Sun is 0.57 degree. Calculate the solid angle subtended by the Sun, in Steradians

C.The solar flux at Earth is F(d) = 1.4 x 10^6 erg/(s*cm^2) use (B) and the Stefan Boltzmann law to derive the effective surface temerature of the Sun

D.Derive an expression for the surface temperature of the Sun, in terms only of its solid angle, its flux per unit wavelength f(lambda1) at Earth at one wavelength (lambda 1) and its fundamental constants
