    • Reflection at plane surfaces: reflection from inclined mirrors at 60°
    • Electrostatics: electrostatic induction in gold leaf electroscopes
    • Current electricity: internal resistance and terminal potential difference across open/closed circuits
    • Nuclear physics: radioactive beta decay equations of Carbon-14 to Nitrogen
    • Electromagnetic spectrum: radiation wavelengths, detection, and applications
    • Magnetism: magnetization by single touch stroking and magnetic poles
    • Sound: speed of sound, echoes, and reflection between two vertical high walls
    • Curved reflectors and thin lenses: image characteristics in plane mirrors versus convex lenses
    • Ohm's law: circuit design, ammeter/voltmeter connections, and variable resistors
    • Power transmission: purpose of the national grid system
    • Electromagnetic force: motor effect, field patterns, and Fleming's left-hand rule
    • Spherical mirrors: ray diagrams and principal focus of concave mirrors
    • Pinhole camera: elimination of internal reflections
  • Section B
    • Capacitors: plate overlap area effects, series-parallel network capacitance, charge, potential difference, and charging voltage-time graphs
    • Waves and physical optics: Young’s double slit interference, shallow-to-deep refraction wavefronts, Snell’s law at water-glass interfaces, dispersion through prisms, and totally reflecting prisms in periscopes
    • Photoelectric effect: definition of work function and threshold wavelength, photocell experiments, and graphical determination of Planck's constant and threshold frequency
    • Electromagnetic induction: Lenz's law, mutual induction between adjacent coils, factors affecting induced e.m.f., and electrical power transmission line losses
    • Cathode Ray Oscilloscope and modern electronics: advantages of CRO over analogue voltmeters, AC wave frequency, peak-to-peak voltage, X-ray production mechanisms, filament heating, target cooling, and lead shielding
