The Electromagnetic Spectrum is a graphic representation of forms of Energy.
- It is normally abbreviated to EM Spectrum.
- It is a quantification of Metrics.
Description (Specifications)
Electromagnetic waves consist of two waves oscillating perpendicular to one another. One of the waves is an oscillating magnetic field; the other is an oscillating electric field. These waves interact with matter, producing different results.
The electromagnetic spectrum is a continuous range of wavelengths. This spectrum includes visible light, X-rays and radio waves. The types of radiation that occur in different parts of the spectrum have different uses and dangers, depending on their wavelength and frequency.
- Radio waves have the lowest frequencies and longest wavelengths, while gamma waves have the highest frequencies and shortest wavelengths.
All of these waves travel at the same speed in free space (the speed of light – about 300,000 km per second).

The EM Spectrum.
TBD
The electromagnetic spectrum shows electromagnetic waves with frequencies ranging from below one hertz to above 1025 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. This frequency range is divided into separate bands, and the electromagnetic waves within each frequency band are called by different names and have a variety of practical applications.
- Radio waves – common uses include communications and television signals
- Microwaves – common uses include food preparation and cellphone signals
- Infrared – common uses include optical fiber systems
- Visible light – Seeing
- Ultraviolet – common uses include detecting forged currency and bioscans
- X-rays – common uses include medical imaging of internal structures
- Gamma radiation – common uses include killing cancerous cells
History & Background (Dossier)
A detailed understanding of the electromagnetic spectrum begins with the development of precise scientific instruments.
Humans form the baseline for visual perception of the electromagnetic spectrum. Different organisms, with different senses, can perceive different regions of the spectrum compared to humans: many Terran creatures can see further into the infrared or ultraviolet.
Other species of creatures and sophonts, originating on worlds orbiting different types of stars and with radically different environments and conditions, may have the ability to view more extreme regions of the spectrum. These are perceived as colors.
