The fundamental properties of matter, EM radiation and introducing quantum phenomena for the first time.
Introduction to Particle Physics
Introduction to Quantum Physics
3.2.1 Particles
Atoms - What is inside these building blocks that make up everything
Specific Charge - The charge to mass ratio
Standard Model - The fundamental particles that make up everything else
Baryons and Mesons - Particles that are made from 2 or 3 quarks
Nuclear Equations - For radioisotopes
Feynman Diagrams - This may look familiar
3.2.2 Electromagnetic Radiation and Quantum Phenomena
Quantum Basics - Photons and the electronvolt
Photoelectric Effect - Electrons in the surface of a metal can interact with photons
Energy Levels - Emission and absorption spectra
de Broglie - Introducing wave-particle duality
