Polarisation

Understand Polarisation of Waves in this clear and exam-focused A-Level Physics lesson! In this video, we explore how transverse waves can be restricted to a single plane of vibration, and why this provides strong evidence that light behaves as a transverse wave. In this lesson, you’ll learn: What is meant by polarisation Difference between transverse and longitudinal waves How a polarising filter works (Polaroid) Why only transverse waves can be polarised Real-life applications: sunglasses, LCD screens, photography, and glare reduction Exam-style questions and common misconceptions Perfect for A-Level Physics students studying waves for Edexcel, AQA, OCR, and other exam boards.
