This GCSE Physics PowerPoint bundle provides a comprehensive series of lessons on electromagnetic waves, covering the electromagnetic spectrum, uses, dangers, and the key required practical. Designed for AQA GCSE Combined Science (Foundation Tier) Physics, these presentations offer detailed explanations, real-world applications, the required practical, and exam-style questions to help students develop a strong understanding of electromagnetic waves. Each lesson includes clear diagrams, structured activities, and revision tasks, making this bundle ideal for both classroom teaching and independent study.

Electromagnetic waves are transverse waves that transfer energy and travel at the speed of light. They are arranged in the electromagnetic spectrum based on their wavelength, frequency, and energy. This bundle explains how different types of electromagnetic waves are used in everyday life, from radio waves for communication to gamma rays for medical treatments, while also exploring potential dangers and safety measures.

What’s Included in the Bundle?
1. Refraction

• Definition of refraction and why light bends at the boundary between two materials.
• Ray diagrams showing how light behaves when passing between air, glass, and water.

2. The Electromagnetic Spectrum

• Definition of electromagnetic waves and their properties.
• Understanding the relationship between wavelength, frequency, and energy.

3. Uses of Electromagnetic Waves

• Real-world applications of radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
• How different waves are used in communication, medical imaging, sterilization, and security.
• Interactive activities and structured tasks to reinforce understanding.

4. Dangers of Electromagnetic Waves

• Identifying which waves are ionising and non-ionising.
• Exploring the risks of X-rays, gamma rays, and ultraviolet radiation.
• Understanding radiation exposure and safety measures in medical and industrial settings.

5. Required Practical – Absorption and Radiation

• Investigating how different surfaces emit and absorb infrared radiation.
• Using Leslie cubes and boiling tubes to compare heat transfer.
• Evaluating results and discussing ways to improve experimental accuracy.

This bundle also includes exam-style questions, structured revision activities, and guided practical investigations. Each PowerPoint is fully editable (.pptx), allowing teachers to adapt lessons to suit their class needs.
