Question 2 · 1 mark · Difficulty 1/3
Which of the following surfaces would MOST effectively reflect sound to produce a clear echo?
- A panel of acoustic foam
- A wall of smooth concrete
- A curtain of heavy fabric
- 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.

CXC CSEC Physics: Sound FAQ
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 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 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 Sound typically tested on CXC CSEC Physics papers?
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.
