PH12-14/Light: Quantum Model
Analyse the experimental evidence gathered about black body radiation, including Wien’s Law related to Planck's contribution to a changed model of light. (ACSPH137).
Investigate the evidence from photoelectric effect investigations that demonstrated inconsistency with the wave model for light. (ACSPH087, ACSPH123, ACSPH137).
Analyse the photoelectric effect as it occurs in metallic elements by applying the law of conservation of energy and the photon model of light. (ACSPH119).
