Question 1 · 1 mark · Difficulty 1/3

Which statement correctly describes the law of reflection?

  1. The angle of incidence equals the angle of reflection, both measured from the surface.
  2. The angle of incidence equals the angle of reflection, both measured from the normal.
  3. The angle of incidence is twice the angle of reflection, both measured from the normal.
  4. The angle of incidence plus the angle of reflection equals 90°.
Show answer & explanation
✓ Answer: B — The angle of incidence equals the angle of reflection, both measured from the normal.
Award 1 mark for identifying that angles are measured from the normal and are equal. A is incorrect — angles are measured from the normal, not the surface. C is incorrect — the angles are equal, not in a 2:1 ratio. D is incorrect — there is no fixed sum; the angles are simply equal to each other.
Question 2 · 1 mark · Difficulty 1/3

An engineer in Japan is testing a new acoustic material for concert hall design. She directs a sound wave at the material at an angle of incidence of 50° to the normal. The material reflects most of the sound energy. What is the angle of reflection?

  1. 40°
  2. 50°
  3. 90°
  4. 100°
Show answer & explanation
✓ Answer: B — 50°
Award 1 mark for 50°. By the law of reflection, the angle of reflection equals the angle of incidence. A is incorrect — this is 90° minus the angle of incidence (measured from the surface, not the normal). C is incorrect — this would mean the wave travels along the surface. D is incorrect — angles are measured from the normal and cannot exceed 90°.

CIE IGCSE Physics: Reflection of waves FAQ

How many CIE IGCSE Physics questions on Reflection of waves are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Reflection of waves for CIE IGCSE 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 CIE 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 CIE IGCSE 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 waves practice with other Physics topics or even switch to a totally different CIE 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 waves questions aligned to the official CIE IGCSE Physics syllabus?
Every question is written against the published CIE IGCSE Physics specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CIE 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 CIE.
How is Reflection of waves typically tested on CIE IGCSE Physics papers?
Reflection of waves appears across multiple question types on real CIE IGCSE 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.
