How to Solve Black Body Radiation Problems with Mathematica?

What is the relation between Rayleigh-Jeans and Planck densities of radiation? How does temperature affect these densities?In summary, the conversation discusses finding the ratio of Rayleigh-Jeans and Planck densities of radiation at the maximum for a black body at a certain temperature, calculating the frequency of the radiation maximum and determining its position on the electromagnetic spectrum, showing the transformation of Planck's equation to Rayleigh-Jeans equation at high temperatures, and deriving the relation between amplitudes in the representation of a plane wave. The use of Mathematica is also mentioned.

Homework Statement



Find the ratio of Rayleigh-Jeans and Planck densities of radiation at the maximum for a black body at T = 5000 K.

Find the frequency of the radiation maximum of a black body at T=3000 K. What part of the electromagnetic radion spectrum does this frequency belong to?

Show that Planck's equation transforms to Rayleigh-Jeans equation at high temperatures (use Series[] function of Mathematica).

Calculate constant b of the second Wien's law (use FindRoot[] of Mathematica)

Derive the relation between the amplitudes in the representation of a plane wave in terms of Cos and Sin waves and in terms of the forward and backward complex exponents




Homework Equations


These questions must be answered with Mathematica...however if someone can give some insight on how to do it by hand, that would be great!

Hmmm... so many questions, so little attempt at a solution...

Start with your first question...what are the relevant equations? How does one find the maximum of a function?
