Describe how frequency changes across the electromagnetic spectrum.

Frequency increases across the electromagnetic spectrum from radio waves through microwaves, infrared, visible light, ultraviolet, X-rays and gamma rays. Students should connect this order to energy and ionising risk without claiming that higher-frequency waves travel faster in a vacuum. The objective is about comparing spectrum positions, so named examples such as radio and gamma are stronger than generic wording about radiation. Within the subtopic Types of electromagnetic waves in Electromagnetic waves, the explanation is anchored to electromagnetic spectrum, frequency and uses those terms in the approved AQA GCSE Physics Waves context.
