Description
Use a photoelectric effect apparatus to investigate the photoelectric effect. Calculate a value for Planck's constant and the work function of the cathode.
Outcomes:
- Develop a practical understanding of the photoelectric effect.
- Calculate a value for Planck's constant and work function of a substance.

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).
