Question

The intensity distribution of solar radiation peaks at a wavelength of approximately 500 nm. Assuming the Sun radiates like a black body, calculate the flux of photons leaving the sun in W/m2

Answer 1

The Sun emits approximately 4*10²⁶ Watts of energy. The light from the sun is found to have a maximum intensity near 470 nm TO 500 nm . Assuming the surface of the sun behaves as a black body,  the flux of solar energy at the Sun-Earth distance is ~1360 W/m² .....
