Transcribed Image Text: 3. Dimensional analysis can provide insight into Stefan-Boltzmann’s law for
the radiation from a black body. According to this law the intensity of
radiation, in units of J s-‘ m-², from a body at temperature Tis
1 = GT*,
where e is Stefan-Boltzmann’s constant. Because black-body radiation
can be considered to be a gas of photons, i.e. quantum particles which
move with velocity e with typical energies of the order of kT, the intensity
I is a function of h, c and kT. Use dimensional analysis to confirm that Iis
proportional to 7 and find the dependence of a on h and c.
