  • Duration: 2 Hours
  • Total Marks: 80
  • Number of Questions: 18 (Questions 1 – 18)
  • Structure: The examination comprises two sections: Section A (25 marks) with 13 compulsory short-answer questions, and Section B (55 marks) consisting of five comprehensive structured calculation and essay questions.

  It covers the following topics:

  • Section A:
    • X-ray production: factors controlling the quality and penetrating power of X-ray beams
    • Magnetism: magnetic polarity testing and domain theory
    • Current electricity: domestic mains lighting circuit connections and conductor resistance determinants
    • Semiconductor physics: doping process and formation of P-type semiconductors
    • Geometrical optics: causes and lens correction of hypermetropia (long-sightedness), and plane mirror rotation
    • Heating and lighting effects: power rating and brightness of bulbs in series
    • Direct current circuits: battery capacity (Ampere-hours) and charge calculations
    • Cathode Ray Oscilloscope (C.R.O): peak voltage and signal frequency determination from time-base settings
    • Wave motion: speed of longitudinal waves along a slinky spring
    • Electrostatics: electrostatic induction on a gold-leaf electroscope
    • Radioactivity: radioactive decay curve interpretation and half-life determination
  • Section B:
    • Electromagnetic induction: Lenz's law, mutual induction demonstration, step-down transformers, turn ratios, efficiency, and transformer power loss reduction
    • Electrostatics and capacitors: factors influencing capacitance, series-parallel capacitor networks, total stored charge, and practical capacitor applications
    • Physical optics and wave phenomena: progressive versus stationary waves, Young's double-slit interference, monochromatic versus white light fringes, and echo sound velocity calculations
    • Refraction of light: Snell's law, real and apparent depth graphs, refractive index, speed of light in media, total internal reflection conditions, and prism periscopes
    • Photoelectric effect: factors affecting photoelectron velocity, work function definitions, Einstein's photoelectric equation, threshold frequency, Planck's constant determination, and metal comparison graphs
