Summary

• Description:

  The PDF document comprises STAREHE GIRLS' CENTRE Physics Paper 2 Pre Mock Exam with Answers (Marking Scheme). The marking scheme is in a different document.

  It was a Pre-mock Physics Paper 2 examination.

  This examination evaluates mastery across geometrical optics, wave phenomena, electrostatics, current electricity, mains wiring, electromagnetism, atomic physics, and basic electronics. It provides thorough revision for candidates preparing for secondary-level physics papers.

  • Duration: 2 Hours
  • Total Marks: 80
  • Number of Questions: 17 (Questions 1 - 17)
  • Structure: Section A (25 marks) comprising 12 structured short-answer questions (questions 1 to 12); Section B (55 marks) containing 5 compulsory extended structured questions (questions 13 to 17).

  It covers the following topics:

  • Section A:
    • Wave phenomena (diffraction differences between light and sound waves)
    • Electromagnetic spectrum (ordering by decreasing wavelength and applications)
    • Vibrations and sound (fundamental frequency and overtone calculations in strings)
    • Refraction of light (relative refractive index calculation)
    • Sound transducers (structural components of a moving-coil microphone)
    • Magnetic effect of an electric current (magnetic field lines around a conductor)
    • Thin lenses (ray diagrams, object-image distance conjugates, and focal length)
    • Mains electricity (high-voltage electrical power transmission)
    • Current electricity (resistor combinations to achieve specific equivalent resistance)
    • Domestic electricity installation (short circuits, fuse placement on live vs neutral lines, and electrical safety)
    • Cathode rays (properties and characteristics)
    • Total internal reflection and practical applications
  • Section B:
    • Geometrical optics (plane mirror rotation, concave mirror magnification formula, convex mirror object distance calculation, and parabolic reflectors)
    • Electrostatics and capacitors (triboelectric charging, definition of capacitance, series-parallel capacitor networks, energy stored in a capacitor, charge distribution on contact, and factors affecting capacitance)
    • Photoelectric effect (threshold wavelength, radiation intensity effects, kinetic energy vs frequency graph plotting, determination of Planck's constant, and work function)
    • Radioactivity and nuclear physics (count-rate decay graph plotting, half-life determination with background radiation correction, beta decay nuclear equation, and medical uses of radioisotopes)
    • Electronics (intrinsic vs extrinsic semiconductors, full-wave bridge rectifier circuits, CRO waveform displays, diode forward and reverse biasing, and network resistance calculations)
