Question 1 · 1 mark · Difficulty 1/3

What is the approximate speed of sound in air at room temperature?

  1. 3 m/s
  2. 30 m/s
  3. 340 m/s
  4. 3000 m/s
Show answer & explanation
✓ Answer: C340 m/s
Award 1 mark for identifying the correct speed of sound in air. A (3 m/s) is far too slow and confuses with walking speed. B (30 m/s) is incorrect and may confuse with typical vehicle speeds. D (3000 m/s) is incorrect — this is closer to the speed of sound in solids such as steel.
Question 2 · 1 mark · Difficulty 2/3

A student connects a microphone to an oscilloscope to display sound waves. Which change to the sound would increase the frequency shown on the oscilloscope trace?

  1. Increasing the loudness of the sound
  2. Decreasing the amplitude of the sound
  3. Increasing the pitch of the sound
  4. Increasing the wavelength of the sound
Show answer & explanation
✓ Answer: CIncreasing the pitch of the sound
Award 1 mark for linking pitch to frequency. A is incorrect — loudness affects amplitude, not frequency. B is incorrect — amplitude is independent of frequency. D is incorrect — increasing wavelength would decrease frequency (v = fλ).

CIE IGCSE Physics: Sound waves FAQ

How many CIE IGCSE Physics questions on Sound waves are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Sound 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 Sound 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 Sound 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 Sound waves typically tested on CIE IGCSE Physics papers?
Sound 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.
