GCSE Physics · key term
The continuous range of electromagnetic waves arranged by frequency or wavelength.
Used by AQA, Edexcel and OCR
Specification 4.6.2.1 · Paper 2
The continuous range of electromagnetic waves, grouped according to wavelength and frequency.
Revise: Types of electromagnetic wavesThe electromagnetic spectrum is continuous: wavelengths and frequencies change gradually, rather than jumping between seven completely separate kinds of wave. We name seven broad groups to make this range easier to describe.
Specification 5.10, 5.11, 7.19P · Paper 1
Do not describe the seven regions as unrelated kinds of radiation: they are adjoining frequency ranges within one electromagnetic spectrum.
State that visible light is only a small part of the electromagnetic spectrum; do not imply that the eye detects the whole spectrum.
Transparent is wavelength-dependent: a material that transmits visible light might absorb another part of the electromagnetic spectrum.

The full continuous range of electromagnetic waves, commonly divided into named groupings.
The electromagnetic spectrum is the full range of these waves. Although we give parts of it different names, it is continuous: there are no gaps between the named groupings.
The continuous range of wavelengths and frequencies that electromagnetic waves can have.
The range of electromagnetic radiation, including radio waves, infrared, visible light, ultraviolet, X-rays and gamma rays.
Specification P5.2d, P5.2e, P5.2g, P6.1i · Paper 2 (Foundation), Paper 4 (Higher)
Revise: EM spectrum groupingsThe electromagnetic spectrum is the continuous range of frequencies and wavelengths that electromagnetic waves can have. Its named regions are useful groupings within that single range; they are not seven unrelated phenomena. Visible light is therefore electromagnetic radiation, just as radio waves and X-rays are.
The complete range of electromagnetic radiation, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays and gamma rays.
The continuous family of transverse waves that includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays and gamma rays.
A complete range of electromagnetic waves arranged by frequency or wavelength, from radio waves to gamma rays.
Paper 1, Paper 2
The complete continuous range of electromagnetic radiation, grouped according to wavelength or frequency.
Revise: Properties of the Electromagnetic SpectrumThe complete range is called the electromagnetic spectrum.
