Summary

• Description:

  The MS Word document comprises Form 4 Physics Schemes of Work Term 3 2025. The PDF version is also available upon your request.

  This scheme of work is designed for use with the Comprehensive Secondary Physics Students' Book 4 and the Secondary Physics KLB Students' Book 4 as the primary reference materials. The curriculum covers three major topics in modern physics: the photoelectric effect, radioactivity, and electronics.

  The topics and their corresponding sub-topics outlined in the document are:

  • Photoelectric Effect
    • Investigating the factors that affect photoelectric emission.
    • Defining and explaining key concepts such as Planck’s constant, threshold frequency, and work function.
    • Applying Einstein’s photoelectric equation ($E=hf + \frac{1}{2}mv^2$) to calculate the energy of photons.
    • Exploring the applications of the photoelectric effect, including photoemissive, photoconductive, and photovoltaic cells.
  • Radioactivity
    • Describing the three types of radiation produced by radioactive elements.
    • Understanding methods for detecting nuclear radiation, such as the diffusion cloud chamber.
    • Defining radioactive decay and half-life.
    • Discussing the hazards of radioactive emissions.
    • Differentiating between nuclear fission and fusion and writing balanced nuclear equations.
  • Electronics
    • Distinguishing between conductors and semiconductors (both intrinsic and extrinsic).
    • Explaining the concept of doping and the working principle of a p-n junction diode.
    • Sketching the current-voltage characteristics of a diode.
    • Explaining the application of diodes in rectification.
