Will a blackbody at temperature $T$ emit more photons-perBsecond with energy $k_{B} T$ or with energy $6 k_{B} T$ ? (Note: The amount of energy emitted per time is not the same as the number of photons emitted per time, though these quantities are related.)
A) It will emit more photons with the lower energy.
B) It will emit more photons with the higher energy.
C) The number of photons emitted will be the same.
D) One has no way of telling.

Question

Quizplus · Accepted Answer

A blackbody emits more photons at lower energies because the number of photons emitted is inversely proportional to their energy, according to Planck's law.
