Year 12 Physics

Module 7 | The nature of light

Content 3: Light: quantum model

Lesson 1 | Black body radiation and Wien's Law

• analyse the experimental evidence gathered about black body radiation, including Wien’s Law ($\lambda _{max} = \frac{b}{T}$) related to Planck’s contribution to a changed model of light (ACSPH137)

Lesson 2 | Photoelectric effect

• investigate the evidence from photoelectric effect investigations that demonstrated inconsistency with the wave model for light (ACSPH087, ACSPH123, ACSPH137)

Lesson 3 | Analysis of the photoelectric effect

• analyse the photoelectric effect ($E_{k} = hf -\Phi$) as it occurs in metallic elements by applying the law of conservation of energy and the photon model of light (ACSPH119)
