Visible Light Spectrum
And light at the upper end of the.
Visible light spectrum. Electromagnetic radiation in this range of wavelengths is called visible light or simply light a typical human eye will respond to wavelengths from about 380 to 740 nanometers. For most of history visible light was the only known part of the electromagnetic spectrum. The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye. In terms of frequency this corresponds to a band in the vicinity of 405 790 thz.
The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. The visible light spectrum is the segment of the electromagnetic spectrum that the human eye can view. Essentially that equates to the colors the human eye can see. Light at the lower end of the visible spectrum having a longer wavelength about 740 nm is seen as red.
Rather the sensation of white is the result of a mixture of two or more colors of light. Light from 400 700 nanometers nm is called visible light or the visible spectrum because humans can see it light outside of this range may be visible to other organisms but cannot be perceived by the human eye. The sensation of white is not the result of a single color of light. The ancient greeks recognized that light traveled in straight lines and studied some of its properties including reflection and refraction the study of light continued and during the 16th and 17th centuries conflicting theories regarded light as either a wave or a particle.
More simply this range of wavelengths is called visible light. The visible light spectrum is shown in the diagram below. When all the wavelengths of the visible light spectrum strike your eye at the same time white is perceived. Typically the human eye can detect wavelengths from 380 to 700 nanometers.
Light in the middle of the spectrum is seen as green.
