The Spectrum of Visible Light |
||||
The Spectrum of Visible LightVisible light is a type of energy (and the tiny part of the electromagnetic spectrum that we can see) The Electromagnetic Spectrum is an ordered series of all types of electromagnetic radiation arranged by wavelength. Electromagnetic radiation, is defined by the length and frequency of the waves in which it travels, and it is measured in nanometers, nm. Each color of light is produced by a specific range of wavelengths.
Most of the sources of light you are familiar with produce electromagnetic radiation of many wavelengths that spread out over a wide range. So while daylight and typical light bulb light appears “clear”, “white” or maybe “yellow”, the truth is that many different wavelengths, each defining a specific color, are spreading out from the source and interfering with each other to create the light we use everyday. |
