The AS Physics exam paper covers key topics in particle physics, mechanics, waves, and electricity. Particle physics examines beta decay, electron antineutrinos, and Feynman diagrams. Mechanics includes forces, energy transformations, and motion concepts like equilibrium, tension, and momentum. Waves explore diffraction, interference, and light path calculations using gratings. Electricity focuses on emf, internal resistance, and energy dissipation in circuits involving resistors and voltmeters. Real-world applications test understanding of optical fibers, modal dispersion, projectile motion, and experimental setups, emphasizing calculations, energy transfers, and graphical analysis.
