Dear classmates...
Using the Planck law, make a spectrum of blackbody radiation graph at five temperatures (one curve must be that of the human body, obligatorily). Make it in intervals of frequencies and of wavelength. The computer program is of free choice.
The spectral radiance of a body, Rν(T), describes the amount of energy it emits at
different radiation frequencies. It is the power emitted per unit area of the
body, per
unit solid angle of emission, per unit frequency. Planck showed (remember that he proposed the idea of quantum and he
introduced the constant that relates the energy and the frequency
of radiation) that the spectral radiance of a body
for frequency ν at absolute
temperature T is
given by ( (use this formula
in a range of frequencies):
where kB is
the Boltzmann constant, h is the Planck constant, and c is the speed of light in the medium, whether material or vacuum.
I would suggest that each curve of the spectrum be of different color.
Give it to me on next Thursday, January 31TH
I send you a fraternal greeting.
