AQA A Level Physics Astrophysics

A comprehensive AQA A Level Physics Astrophysics revision PowerPoint designed for classroom teaching, intervention, retrieval practice and exam preparation.

Each major topic begins with Do Now (DNA) retrieval questions followed by a separate answer slide for immediate feedback and correction. Key knowledge is presented using a Cornell note-taking structure with Cues/Questions, Main Notes and Summary sections to help students organise, retrieve and review essential ideas.

After each key point, students complete three short-answer whiteboard questions testing knowledge, understanding and common misconceptions. Answers are provided for rapid assessment and correction. Longer book-work questions are followed by worked solutions and detailed revision notes.

Topics include:
• Refracting and reflecting telescopes
• Cassegrain telescopes
• Chromatic and spherical aberration
• CCDs, human eye comparison and quantum efficiency
• Optical and radio telescopes
• Angular resolution and Rayleigh criterion
• Apparent and absolute magnitude
• Luminosity, intensity and inverse square law
• Parallax, parsecs and light years
• Wien’s law and Stefan’s law
• Stellar spectral classes
• Hertzsprung–Russell diagrams
• Supernovae, neutron stars and black holes
• Red shift, Doppler effect and Hubble’s law
• Big Bang evidence, quasars, dark matter and dark energy
• Exoplanet detection methods

Designed for whole-class display with clear layouts, large readable text, worked examples and exam-focused practice.
