Answer:
given = photon = 1000L
convert the given radiation of photons in the joule.
1000L = 747X10³
temprature = 500K 5X 10⁻¹⁹
energy of one photon = 2.96
to find = number of photons
solution =
total energy = 7.47 X 10³/ 2.965 X 10⁻¹⁹
= 2.52 X10¹⁵
the number of photons in 1000L of radiation in a thermal equilibrium at 500 K is 2.52 X10¹⁵photons.
