Question 1 · 1 mark · Difficulty 1/3

What is thermal radiation?

  1. Energy transferred by moving particles of a fluid
  2. Energy transferred as electromagnetic waves, mainly infrared
  3. Energy transferred by direct contact between solids
  4. Energy stored inside a hot object
Show answer & explanation
✓ Answer: BEnergy transferred as electromagnetic waves, mainly infrared
It needs no medium, which is why the Sun's energy reaches us through space.
Question 2 · 1 mark · Difficulty 1/3

Which objects emit thermal radiation?

  1. Only black-coloured objects
  2. All objects above absolute zero
  3. Only objects hotter than their surroundings
  4. Only objects that are glowing
Show answer & explanation
✓ Answer: BAll objects above absolute zero
Even a cold object emits some radiation; it simply emits less than a hot one.

AQA GCSE Physics: Black body radiation and emission of radiation FAQ

Is Kramizo free for AQA GCSE 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 Black body radiation and emission of radiation practice with other Physics topics or even switch to a totally different AQA 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 Black body radiation and emission of radiation questions aligned to the official AQA GCSE Physics syllabus?
Every question is written against the published AQA GCSE Physics specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real AQA 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 AQA.
How is Black body radiation and emission of radiation typically tested on AQA GCSE Physics papers?
Black body radiation and emission of radiation appears across multiple question types on real AQA GCSE 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.
