#6 The Planck Distribution Function
An object in thermal equilibrium will radiate heat through a process known as
"blackbody radiation," where all properties of the radiation are determined by the body's
temperature. In quantum mechanics, radiation means that massless particles called
photons carry energy away from the body. All electromagnetic radiation (including
visible light) consists of photons. Each photon carries energy equal to hc/
, where
is
the wavelength of the photon, h is the Planck constant (6.6 x 10
34
Joulesec in SI units),
and c is the speed of light.
Blackbody radiation is given by the Planck Distribution Function, which says that the
