Light Spectrum In Nanometers

Visible light is usually defined as having wavelengths in the range of 400 700 nanometers nm or 4 00 10 7 to 7 00 10 7 m between the infrared with longer wavelengths and the ultraviolet with shorter wavelengths.

Light spectrum in nanometers. It is also known as the optical spectrum of light or the spectrum of white light. We can detect the range of light spectrum from about 400 nanometers violet to about 700 nanometers red and after this range the human eye is unable to see the rest of the electromagnetic waves. The wavelength range of electromagnetic radiation that falls between 380 nanometers to 750 nanometers constitutes the visible light spectrum 1 nanometer 10 9 meter these are the two limits beyond which the human eye cannot perceive any colors as the biological mechanism in the retina which makes color vision possible does not respond to frequencies that have a wavelength greater. Ir wavelengths extend from the nominal red edge of the visible spectrum at.

Expressed in more familiar units the range of wavelengths extends from 7 x 10 7 meter to 4 x 10 7 meter. This visible light region consists of a spectrum of wavelengths that range from approximately 700 nanometers abbreviated nm to approximately 400 nm. Essentially that equates to the colors the human eye can see. The human eye sees color over wavelengths ranging roughly from 400 nanometers violet to 700 nanometers red.

In terms of frequency this corresponds to a band in the vicinity of 405 790 thz. Ultraviolet uv is a form of electromagnetic radiation with wavelength from 10 nm with a corresponding frequency of approximately 30 phz to 400 nm 750 thz shorter than that of visible light but longer than x rays uv radiation is present in sunlight and constitutes about 10 of the total electromagnetic radiation output from the sun it is also produced by electric arcs and specialized. In the electromagnetic spectrum the visible spectrum ranges from the infrared region to the uv region. Passing white light through a prism splits it up into the several colors of light observed in the visible spectrum between 400 nm and 780 nm.

It ranges in wavelength from approximately 400 nanometers 4 x 10 7 m which is violet to 700 nm 7 x 10 7 m which is red. 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 visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye. Light or visible light is electromagnetic radiation within the portion of the electromagnetic spectrum that can be perceived by the human eye.

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.
