The electromagnetic spectrum is the complete range of electromagnetic waves arranged according to their wavelengths or frequencies.

In GCSE Physics, it is important to understand that this spectrum includes, from longest wavelength to shortest, radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.

Each type of wave has different properties and uses; for example, radio waves are used for broadcasting, while X-rays are used in medical imaging.

The electromagnetic spectrum is crucial because it encompasses all the different forms of electromagnetic radiation, which are essential for various technologies and scientific applications.
