What Is Visible Light
What is the visible light spectrum.
What is visible light. As you can tell by the name visible light is the light that humans can see. It is also known as the optical spectrum of light or the spectrum of white 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. Typically the human eye can detect wavelengths from 380 to 700 nanometers.
Visible light is a form of electromagnetic em radiation as are radio waves infrared radiation ultraviolet radiation x rays and microwaves. The visible spectrum is the portion of the electromagnetic spectrum between infrared and ultraviolet infrared radiation microwaves and radio waves are lower. The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye. Visible light is the part of the electromagnetic spectrum that falls between infrared and ultraviolet radiation.
Green plants are green because they absorb all of the colors of the visible spectrum except the green color you could also say the green wavelengths. Essentially that equates to the colors the human eye can see. The visible light spectrum is the segment of the electromagnetic spectrum that the human eye can view. Visible light is a range of electromagnetic radiation that can be detected by the human eye the wavelengths associated with this range are 380 to 750 nanometers nm while the frequency range is approximately 430 to 750 terahertz thz.
The portion of the spectrum where visible light can be found corresponds closely to the short wavelength less than 5 cm light that best penetrates the earth atmosphere s optical window. 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. 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.
