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).
