This educational resource explains how Maxwell’s equations lead to the prediction of electromagnetic waves. It introduces the key physical idea that changing electric and magnetic fields are linked, and shows how this relationship allows electromagnetic waves to travel through vacuum at the speed of light. The resource is designed for students preparing for university-level physics and engineering. It connects Maxwell’s equations with plane electromagnetic waves, the relationship between electric and magnetic field amplitudes, the speed of light, antennas, wireless communication, optical fibres, radar, and other modern technologies. The material includes conceptual explanations, visual illustrations, worked examples, review questions, thought-provoking questions, numerical problems, a glossary, and external references. This work is part of Prep4Uni.online, an independent, free online learning hub for university preparation and career readiness.
