Wavelengths Of Visible 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.

Wavelengths of visible light. Violet has the shortest wavelength at around 380 nanometers and red has the longest wavelength at around 700 nanometers. 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. Visible light is known to have wavelengths in the range of 400 to 700 nanometres nm or 4 00 10 to 7 00 10 m which is between infrared which has longer wavelengths and ultraviolet which has shorter wavelengths. The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye.

The spectrum of visible light has about numerous different colours having different wavelengths. The visible light spectrum is located within a wavelength range of 380 to 740 nanometers nm or frequency range of 405 to 790 terahertz thz. The wavelengths of the visible light is ranging from 400 to 700 nanometers nm. Different animals are sensitive to different wavelengths for example snakes are sensitive to infrared wavelengths so they can detect infrared light and some insects can detect ultraviolet light.

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. The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye.

Hence it is called visible light. 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 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 waves travel at very high speeds and are absorbed or reflected by various objects.

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. It is also known as the optical spectrum of light or the spectrum of white light. Since visible light is a form of a wave it is defined by its characteristic wavelength and frequency.
