Question 1 · 1 mark · Difficulty 1/3

A teacher in St. Lucia demonstrates reflection using a laser pointer and a plane mirror. She draws a diagram showing the incident ray, normal and reflected ray. Which angle must be measured to determine the angle of incidence?

  1. The angle between the incident ray and the mirror surface
  2. The angle between the incident ray and the normal
  3. The angle between the incident ray and the reflected ray
  4. The angle between the reflected ray and the mirror surface
Show answer & explanation
✓ Answer: BThe angle between the incident ray and the normal
Award 1 mark for correct answer. By definition, the angle of incidence is always measured between the incident ray and the normal to the surface at the point of incidence. A is incorrect because this gives the complement of the angle of incidence. C is incorrect because this is the sum of angles of incidence and reflection. D is incorrect because this relates to the reflected ray, not incident ray.
Question 2 · 1 mark · Difficulty 2/3

During a physics practical in Guyana, students investigate reflection using a ray box and plane mirror. They notice that when the angle of incidence is 0°, the reflected ray travels back along the same path as the incident ray. What is the angle of reflection in this case?

  1. 45°
  2. 90°
  3. 180°
Show answer & explanation
✓ Answer: A
Award 1 mark for correct answer. When the incident ray is along the normal (angle of incidence = 0°), the angle of reflection is also 0° according to the law of reflection. The ray reflects back along the normal. B is incorrect as 45° would require an incident angle of 45°. C is incorrect because 90° is the angle between the normal and the mirror surface. D is incorrect as 180° is not possible for reflection.

CXC CSEC Physics: Reflection of Light and the Law of Reflection FAQ

How many CXC CSEC Physics questions on Reflection of Light and the Law of Reflection are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Reflection of Light and the Law of Reflection for CXC CSEC Physics, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real CXC paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for CXC CSEC students preparing for Physics?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Reflection of Light and the Law of Reflection practice with other Physics topics or even switch to a totally different CXC subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Reflection of Light and the Law of Reflection questions aligned to the official CXC CSEC Physics syllabus?
Every question is written against the published CXC CSEC Physics specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CXC paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from CXC.
How is Reflection of Light and the Law of Reflection typically tested on CXC CSEC Physics papers?
Reflection of Light and the Law of Reflection appears across multiple question types on real CXC CSEC Physics papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
