AQA A Level Physics Paper 3bb 2025 Question Paper

Download the official AQA A-Level Physics Paper 3 Section B Medical Physics question paper from the June 2025 examination series (7408/3BB). This examiner-authentic PDF contains the complete Medical Physics optional-topic assessment used in the live AQA A-Level Physics examination. The paper covers eye accommodation, optical power, hypermetropia, radioactive tracers, technetium-99m generators, MUGA scans, ultrasound imaging, hearing thresholds, equal-loudness curves, X-ray production, focal spots, radiation safety, and X-ray attenuation through bone from the AQA Medical Physics specification.

This 35-mark Paper 3BB assessment includes structured calculations, graph interpretation, extended written explanations, medical-imaging analysis, and applied Physics reasoning questions designed to test advanced conceptual understanding and mathematical skills under real AQA exam conditions. Major topics featured in the paper include accommodation amplitude and focal-length calculations for the human eye, technetium-99m decay and activity graphs, comparison of MUGA and transthoracic echocardiogram (TTE) scans, threshold-of-hearing definitions, equal-loudness curve interpretation, sound-intensity power calculations, rotating-anode X-ray tube focal spots, patient radiation protection methods, and attenuation of X-ray photons through a femur cross-section.

The paper also contains realistic healthcare and diagnostic-imaging contexts involving ultrasound transducers, radioactive tracers bound to red blood cells, hearing tests, and diagnostic X-ray procedures. Ideal for timed practice, mock examinations, Medical Physics revision, and advanced exam-technique preparation before the 2026 A-Level Physics examinations. Pair this paper with the matching AQA 7408/3BB 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 and taking the Medical Physics optional topic, especially Year 13 students preparing for the 2026 examination series. It is particularly valuable for students targeting high grades who need authentic practice with medical-imaging calculations, radiation Physics, sound-intensity analysis, and healthcare-application 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 Medical Physics resources for mock examinations, classroom assessments, topic testing, homework tasks, and structured revision programmes. It helps learners strengthen mathematical reasoning, graph interpretation, scientific explanation skills, and applied Medical Physics understanding before the 2026 examinations.
