1. FUNDAMENTAL OD RADIATIVE TRANSFER
Ch1.1 The spectrum correspond to waves which have various wavelength and frequency. λν=c Temperature and energy E=hν T=E/k
ch1.2 Flux = the measure of energy of all rays passing through a given area dAdt. Flux from isotropic source = assuming there are two spherical sources S and S' with radii r and r'. by conservation of energy, energy passing both elements are the same; F(r)*4πr^2 = F(r')*4πr'^2. => F= const/r^2 if S' is fixed.
ch1.3 radiation is the energy carried by individual rays, but we need to consider the energy carried by sets of rays rather than individual ray because single ray essentially does not carry energy.
