Question 1 · 1 mark · Difficulty 1/3

What is meant by the term 'red-shift' when applied to light from distant galaxies?

  1. The light appears red in colour to observers on Earth
  2. The wavelength of light is increased compared to light from a stationary source
  3. The wavelength of light is decreased compared to light from a stationary source
  4. The light has been absorbed by red dust particles in space
Show answer & explanation
✓ Answer: BThe wavelength of light is increased compared to light from a stationary source
Award 1 mark for identifying that red-shift means the wavelength of light is increased (shifted towards the red end of the spectrum). A is incorrect — red-shift refers to a change in wavelength, not the actual colour observed. C describes blue-shift, which occurs when objects move towards the observer. D is incorrect — red-shift is a Doppler effect, not caused by absorption.
Question 2 · 1 mark · Difficulty 2/3

The Big Bang theory is the currently accepted model for the origin of the Universe. Which piece of evidence does NOT support the Big Bang theory?

  1. The red-shift of light from distant galaxies
  2. The existence of cosmic microwave background radiation
  3. The observation that distant galaxies appear smaller
  4. The abundance of hydrogen and helium in the Universe
Show answer & explanation
✓ Answer: CThe observation that distant galaxies appear smaller
Award 1 mark for identifying that distant galaxies appearing smaller is simply due to perspective and distance, not evidence for the Big Bang. A is incorrect — red-shift supports the expanding Universe predicted by the Big Bang theory. B is incorrect — CMBR is the 'afterglow' of the Big Bang and strong evidence for it. D is incorrect — the predicted ratio of H:He from Big Bang nucleosynthesis matches observations.

CIE IGCSE Physics: Space physics — the expanding universe and red-shift FAQ

How many CIE IGCSE Physics questions on Space physics — the expanding universe and red-shift are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Space physics — the expanding universe and red-shift 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 Space physics — the expanding universe and red-shift 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 Space physics — the expanding universe and red-shift 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 Space physics — the expanding universe and red-shift typically tested on CIE IGCSE Physics papers?
Space physics — the expanding universe and red-shift 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.
