AQA A Level Physics Paper 3ba 2025 Question

Download the official AQA A-Level Physics Paper 3 Section B Astrophysics question paper from the June 2025 examination series (7408/3BA). This examiner-authentic PDF contains the complete Astrophysics optional-topic assessment used in the live AQA A-Level Physics examination. The paper covers black-body radiation, Wien’s displacement law, astronomical telescopes, CCD imaging, binary-star systems, apparent and absolute magnitude, Hubble’s law, dark energy, stellar spectra, eclipsing binaries, and luminosity-distance relationships from the AQA Astrophysics specification.

This 35-mark Paper 3BA assessment includes structured calculations, extended written explanations, graph interpretation, ray-diagram construction, and applied Astrophysics reasoning questions designed to test advanced conceptual understanding and mathematical analysis under real AQA exam conditions. Major topics featured in the paper include black-body curves for HIP 56948, Earth-like exoplanet detection challenges, refractor and reflector telescope comparisons, CCD detector advantages, recessional velocity calculations for galaxy M87 using Hubble’s law, evidence for dark energy, binary-star magnitude analysis involving Mintaka Aa1 and Mintaka Aa2, eclipsing binary light curves, orbital angular velocity, and luminosity changes for Betelgeuse.

The paper also contains realistic astronomy contexts involving Mars observations, active supermassive black holes, stellar spectral classification, and observational astronomy techniques. Ideal for timed practice, mock examinations, Astrophysics revision, and advanced exam-technique preparation before the 2026 A-Level Physics examinations. Pair this paper with the matching AQA 7408/3BA mark scheme on markscheme.net for complete examiner-standard revision, accurate self-assessment, and performance improvement using authentic AQA standards.

This document is designed for AQA A-Level Physics students studying the 7408 specification, particularly Year 13 students taking the Astrophysics optional topic and preparing for the 2026 examination series. It is especially valuable for students targeting high grades who need authentic practice with advanced Astrophysics calculations, telescope analysis, binary-star systems, and observational-astronomy questions under timed exam conditions.

The paper is also highly useful for Physics teachers, tutors, sixth-form colleges, revision centres, home-schooled learners, and retake candidates who require official AQA exam-standard Astrophysics resources for mock examinations, classroom assessments, topic testing, homework tasks, and structured revision programmes. It helps learners strengthen mathematical reasoning, scientific explanation skills, graph interpretation, and applied Astrophysics understanding before the 2026 exams.
