Electromagnetic waves

Electromagnetic waves

An electromagnetic wave transfers energy through oscillating electric and magnetic fields. The oscillations are perpendicular to the direction of energy transfer, so every electromagnetic wave is transverse.

5.2 The electromagnetic spectrum Lesson

  1. GCSE
  2. /Physics
  3. /5.2 The electromagnetic spectrum

Step-by-step lessons on Edexcel GCSE Physics 5.2 The electromagnetic spectrum, covering 5.2.1 Electromagnetic waves and refraction in glass (core practical), 5.2.2 Groups of the electromagnetic spectrum, 5.2.3 Wavelength-dependent behaviour of EM waves, and 5.2.4 Velocities of EM waves in different substances. Each one builds up to exam-style questions. Master the required practical work and core equations early, since both papers can draw on content and maths skills from across the whole specification.
