Assuming that the sun is a spherical blackbody with a radius of 7 x 10

1.	Assuming that the sun is a spherical blackbody with a radius of 7 x 108 m. Calculate the sun’s temperature and the radiation energy density within it.
Answer» E = σ AT⁴ \(\because\) A = 4πR² E = σ T⁴ . 4πR² \(\cfrac{E}{σ4\pi R^2}\) = T⁴ T = \((\cfrac{E}{σ4\pi R^2})^{1/4}\)

Assuming that the sun is a spherical blackbody with a radius of 7 x 108 m. Calculate the sun’s temperature and the radiation energy density within it.

Answer»

E = σ AT⁴

\(\because\) A = 4πR²

E = σ T⁴ . 4πR²

\(\cfrac{E}{σ4\pi R^2}\) = T⁴

T = \((\cfrac{E}{σ4\pi R^2})^{1/4}\)
