This bundle includes fully resourced, meticulously structured presentations covering the entirety of the AQA A-Level Physics 3.12.2 Wave-Particle Duality sub-topic.

This PowerPoint bundle includes:

• Lesson 1: 3.12.2.1 - Newton’s Corpuscular Theory of Light (Emission theory, explanation of reflection/refraction, and shortcomings)
• Lesson 2: 3.12.2.2 - Significance of Young’s Double-Slit Experiment (Interference fringes, wave model supremacy over corpuscular theory, and path difference)
• Lesson 3: 3.12.2.3 - Electromagnetic Waves (Maxwell’s formula, Hertz’s discovery of radio waves, and Fizeau’s determination of the speed of light)
• Lesson 4: 3.12.2.4 - The Discovery of Photoelectricity (Threshold frequency, work function, Einstein’s photoelectric equation, and failure of wave theory)
• Lesson 5: 3.12.2.5 - Wave-Particle Duality (De Broglie’s hypothesis, momentum relationship, and electron diffraction confirmation)
• Lesson 6: 3.12.2.6 - Electron Microscopes (Transmission Electron Microscope (TEM) and Scanning Tunneling Microscope (STM), resolving power, and operating principles)

Every lesson in this bundle consists of:

Do Now / Starters: Immediate engagement and recall of previous lessons.

I Do, We Do, You Do: A highly scaffolded approach to problem-solving, moving from modeled examples to independent practice.

Misconception Busting: Dedicated slides in every lesson addressing common exam pitfalls.

Diagrams: Cohesive diagrams to support with explanations and abstract concepts.

Fully Animated Solutions: Step-by-step working for all practice questions.

Plenaries & Summaries: Built-in review checks to assess understanding before the lesson ends.
