Four ways electromagnetic waves interact

Four ways electromagnetic waves interact

Electromagnetic waves such as visible light, infrared, ultraviolet and X-rays can meet materials in different ways. The four key interactions are absorption, transmission, reflection, and refraction.

5.3 Wave interactions Lesson

  1. GCSE
  2. /Physics
  3. /5.3 Wave interactions

Step-by-step lessons on OCR GCSE Physics 5.3 Wave interactions, covering 5.3.1 Wavelength and how substances affect waves, 5.3.2 Wave velocity in different substances, 5.3.3 Convex and concave lenses, 5.3.4 Ray diagrams for reflection and refraction, and 5.3.5 Colour, absorption and reflection. Each one builds up to exam-style questions. Paper 2 and Paper 4 include synoptic questions that draw on Topics P1–P4, so revisit earlier topics before final exams rather than treating each paper as self-contained.
