SP5d Electromagnetic Waves | Edexcel GCSE Physics Separate Science Topic Mastery Pack

A focused three-component revision and exam practice pack for SP5d, covering the complete Edexcel Separate Science Physics specification for electromagnetic wave properties (P5.7, P5.8, P5.12, P5.14).

Topic Mastery Sheet covers all properties shared by every electromagnetic wave; the speed of EM waves in a vacuum; the part of the spectrum detectable by the human eye; how EM radiation transfers energy from source to observer; and what happens to an atom when it absorbs electromagnetic radiation. The distinction between EM waves (can travel through a vacuum) and mechanical waves is highlighted.

Student Exam Practice Sheet includes a multiple choice question on detection of EM waves, a three-part properties question, a question on transverse waves that are not electromagnetic, a question on what happens when an atom absorbs radiation, and an explanation question using the Sun’s radiation reaching Earth as context. Question format matches the Edexcel test.

Teacher Answer Key provides a complete mark scheme with guidance on which atomic-level changes are creditworthy and what the energy-transfer explanation requires for each mark.
