Sec 1.3 Blackbody Radiation

Plank's Law (Wikipedia)
- All objects are essentially "hot" (considering the concept of absolute zero).
- All (hot) objects radiate light (electromagnetic radiation).
- The wavelength/frequency of the light emitted from a (hot) object is related to the temperature of the object.
- We can make a graph of wavelength (λ) or frequency (ν) as a function of temp (T), but at any given temperature light emitted has a range of λ or ν. So instead we develop some expressions using the term spectral density (ρ - rho).

Meet in CSB 378

PLEASE make an entry in your lab notebook

Activity 1: Mathematica

- Basic Plot statement
  • Plot[x^2, {x, 0, 10}]
- Plotting 2 function on one graph
  • Plot[{x^2, X^3}, {x, 0, 10}]
- "Manipulate" a Plot
  • Manipulate[Plot[{a*x^2, a*x^3}, {x, 0, 10}], {a, 1, 2}] ...with y-axis range defined
  • Manipulate[Plot[{a*x^2, a*x^3}, {x, 0, 10}, PlotRange -> {0, 2000}], {a, 1, 2}]
Challenge: Reproduce the Figure 1.2 above for Plank's Blackbody Radiation (spectral density vs frequency)
- First try and use the "Manipulate" function, then do the plot of 5 functions.
- See here for the function (slightly different than book) --> Plank's Law (Wikipedia)
