Official WAEC Physics outline · Part V & Harmonised Topics: Atomic, Nuclear, and Advanced Physics

Content

Atomic models (Rutherford, Bohr), energy levels, line spectra, photoelectric effect, Einstein's equation, thermionic emission, X-rays, nuclear composition, isotopes, natural/artificial radioactivity, half-life, nuclear fission/fusion, mass defect ($E=\Delta m c^2$), wave-particle duality, dimensional analysis, projectile motion calculations, satellites/rockets, Hooke's law/Young's modulus, thermal conductivity/blackbody, fiber optics, LASERs, and semiconductor physics (doping, p-n junction diodes, rectification)

Objective

Compare atomic models and calculate energy level transitions; explain photoelectric work function, threshold frequency, thermionic emission, and X-ray production; compute radioactive decay, half-life, mass defect, and nuclear binding energy; verify dimensional correctness of equations; solve projectile range, maximum height, and time of flight problems; analyze satellite orbits and elastic properties (Hooke's law, Young's modulus); explain blackbody radiation, fiber optics, and LASER applications; distinguish conductors, intrinsic/extrinsic semiconductors, and p-n junction diode rectification.
