Electromagnetic Spectrum (EF)

Abstract EMF Illustration

Different types of energy can be characterized by the frequency in which it occurs—its wavelength. The Electromagnetic Spectrum is a classification system used by scientists to classify and study different frequencies of energy.

The energy that has a more frequent (higher) wavelength falls higher on the electromagnetic spectrum. Common high-frequency energies include UV light, gamma radiation, X-Rays, and cosmic rays. Lower-wavelength energy sources include visible light, microwaves, and radio waves.

Visible light falls within a very small relative portion of the electromagnetic spectrum. That’s to say, the human eye is only capable of perceiving a very small portion of the electromagnetic energy that surrounds us. Certain bands of energy such as Infrared light and ultraviolet light are just outside of our ability to see.

This image from NASA shows the relative size of the bands of electromagnetic energy:

This EM Diagram illustrates the relatively small frequency of light visible to the human eye.

Other mammalian species have been shown able to perceive ultraviolet lights (R). This would, in effect, mean that some of our favorite animal companies experience a very different objective reality than our own. Humans are limited to vision within the~700nm – 400nm range which spans across “colors” including red, orange, yellow, green, blue, indigo, and violet (Roy G. Biv).
