Lo Spettro Elettromagnetico La luce puo’ essere caratterizzata da Lunghezza d’onda: , misurata in m, mm, cm, Å. Frequenza: , misurata in Hz, MHz. Energy: E, misurata in erg, Rydbergs, eV, keV, MeV, GeV. Temperatura: T Le differenti quantita’ si ottengono dalle relazioni:   = c E = h  T = E/k dove c = 2.9979245800 × 1010 cm s-1 h = 6.62606876 × 10-27 erg s k = 1.3806503 × 10-16 erg K-1
