[b]Spectral radiance B: Spectral distribution of an ideal "Black Body" at temperature equilibrium[/b]
[i]Why do hot things glow? And why do really hot things shine, like the sun?
How hot is the sun's surface? How do we know how far other stars are away?[/i]
All this Questions can be answered with the help of Max Karl Ernst Ludwig Planck's Equation!
On the way I [b]solved [/b]two other open problems:
[b]1.: Logarithmic scaling: Just compare B_f and B_{f-log}.
2.: Easy dynamic coloring: Have a look on the hidden "Graphics2"-Screen and the "Auxilary Objects"[/b]
The colors are just symbolic. This is because of the limited range of computer screens. 1800K hot plates glow brighter red than in the scale. At 10000K the intensity would instantly blind you.
If you do [b]NOT [/b]like it, leave a comment.
I am also interested in your diffculties or (possible) missunderstandings.
