SUMMARY
The photon flux at a distance of 1 km from a light source emitting 50W of radiation in the visible domain, specifically at a wavelength of 6000 Angstroms, is calculated to be 1.20 x 1013 photons/m2s. The energy of one photon is determined using the formula E = hc/λ, resulting in an energy value of 3.32 x 10-19 J. The calculation of the number of photons per second is confirmed to be 1.51 x 1020, with a consensus that this value was initially misrepresented as a typo.
