In AQA A-Level Physics, telescopes are covered under the Astrophysics unit, focusing on refracting and reflecting telescopes. Refracting telescopes use lenses to collect and focus light but suffer from chromatic aberration and lens size limitations. Reflecting telescopes use mirrors, avoiding chromatic aberration and allowing larger apertures. Key concepts include focal length, magnification, resolving power, and diffraction limits. Radio telescopes also feature, gathering radio waves rather than visible light. Comparisons between optical and radio telescopes in terms of wavelength, resolution, and use in astronomy are highlighted.
