  It covers the following topics:

  • Reflection of light using plane mirrors (ray tracing and angles of reflection)
  • Electromagnetic spectrum (ordering radiations by energy and detecting radio waves)
  • Radioactivity and nuclear decay (alpha and beta emissions; radium to lead)
  • Electric power in resistive devices (heater power calculation)
  • Sound and echoes (distance to a reflector using time delay)
  • Resistors in combination (designing a network to achieve a required effective resistance)
  • Thermal expansion effects and reflection (mirror suspended by a rubber band and change in reflected ray angle)
  • Pinhole camera conditions for same-size images
  • Properties of X-rays compared with visible light
  • Waves (interpreting waveforms and determining wave velocity)
  • Semiconductors (reverse biasing a p-n junction diode)
  • Magnetism and force on a current-carrying conductor (direction and determining factors)
  • Electromagnetic induction (Faraday’s law; simple generator parts and improving bulb brightness)
  • Transformers (step-up requirements, current calculations, turns ratio, and reducing eddy/hysteresis losses)
  • Refraction and refractive index (critical angle calculations)
  • Human eye and vision (accommodation, identifying a defect, and showing correction)
  • Lenses (image position for a concave lens using focal length and object distance)
  • Electrostatics (factors affecting force; charge distribution using a proof plane and electroscope)
  • Capacitors (charging/discharging, resultant potential difference, and uses of capacitors)
  • Mirrors (concave mirror ray diagram; determining focal length from a graph; slopes and readings)
  • Electricity safety (3-pin plug terminals, wiring mistakes, and why the earth pin is longer)
  • Photoelectric effect (threshold wavelength, Planck’s constant from a graph, and work function)
