Visible Light Wavelength

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.

Visible light wavelength. In terms of frequency this corresponds to a band in the vicinity of 405 790 thz. Violet has the shortest wavelength at around 380 nanometers and red has the longest wavelength at around 700 nanometers. 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. Wavelength of the visible light ranges between 400 nm to 700 nm and here we come to know the wavelength of various colours of the visible spectrum of light.

As the full spectrum of visible light travels through a prism the wavelengths separate into the colors of the rainbow because each color is a different wavelength. 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. It is also known as the optical spectrum of light or the spectrum of white light. Essentially that equates to the colors the human eye can see.

Light or visible light is electromagnetic radiation within the portion of the electromagnetic spectrum that can be perceived by the human eye. The human eye sees color over wavelengths ranging roughly from 400 nanometers violet to 700 nanometers red. 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.
