Summary

• Description:

  The MS Word document comprises the Form 3 Physics Paper 3 End Term 2 2025 Exam with Marking Scheme. The PDF version is also available upon your request. The marking scheme is in a different document.

  The practical exam paper contains 2 questions. It is marked out of a total of 42 marks and should be completed by learners within a duration of 2 ½ hours.

  The exam requires learners to perform and report on two experiments:

  • Question 1: Optics - Refraction of Light 💡
    This experiment investigates the refraction of light through a rectangular glass block. Students are required to measure angles of incidence and refraction for various rays , plot a graph of Sin i against Sin r , and use the graph to determine the refractive index (as the gradient) and the critical angle of the glass.
  • Question 2: Mechanics - The Simple Pendulum pendulum
    This experiment involves setting up a simple pendulum and measuring the time for 10 oscillations at different lengths of the string. Learners must then calculate the period and frequency, plot a graph of F² against 1/L , and use the graph's slope to determine the value of 'g', the acceleration due to gravity.
