Electromagnetic Waves - GCSE Physics Definition

Electromagnetic waves are a type of wave that carries energy through space and are created by the movement of electrically charged particles. These waves do not require a medium to travel through, meaning they can move through a vacuum, such as space. T

hey are characterised by their changing electric and magnetic fields, which oscillate at right angles to each other and the direction of wave travel.

Electromagnetic waves vary in wavelength and frequency, forming the electromagnetic spectrum, which includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Understanding electromagnetic waves is crucial for GCSE Physics, as they are fundamental to many technologies, including mobile phones, radios, and medical imaging.
