Question 1 · 1 mark · Difficulty 1/3

Which of the following surfaces would MOST effectively reflect sound to produce a clear echo?

  1. A panel of acoustic foam
  2. A wall of smooth concrete
  3. A curtain of heavy fabric
  4. A hedge of dense bushes
Show answer & explanation
✓ Answer: B — A wall of smooth concrete
Hard, smooth, dense surfaces like concrete reflect sound efficiently, producing clear echoes. Heavy fabric, acoustic foam, and dense bushes are soft or irregular materials that absorb or scatter sound energy, reducing or preventing echo formation.
Question 2 · 1 mark · Difficulty 1/3

Which property of sound is best demonstrated when a loud clap produces an echo inside a large empty concrete building?

  1. Diffraction of sound waves
  2. Absorption of sound waves
  3. Reflection of sound waves
  4. Refraction of sound waves
Show answer & explanation
✓ Answer: C — Reflection of sound waves
An echo is produced when sound waves strike a hard surface and bounce back to the listener — this is reflection. Refraction involves bending of waves at boundaries between media. Diffraction involves spreading around obstacles. Absorption occurs when sound energy is converted to heat in soft materials, reducing echo.

CXC CSEC Physics: Reflection and Echoes of Sound FAQ

How many CXC CSEC Physics questions on Reflection and Echoes of Sound are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Reflection and Echoes of Sound 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 and Echoes of Sound 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 and Echoes of Sound 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 and Echoes of Sound typically tested on CXC CSEC Physics papers?
Reflection and Echoes of Sound 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.
