The visible spectrum is the portion of the electromagnetic spectrum that is visible to 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 390 to 700 nm. In terms of frequency, this corresponds to a band in the vicinity of 430–770 THz.
The spectrum does not, however, contain all the colors that the human eyes and brain can distinguish. Unsaturated colors such as pink, or purple variations such as magenta, are absent, for example, because they can be made only by a mix of multiple wavelengths. Colors containing only one wavelength are also called pure colors or spectral colors.
Visible wavelengths pass through the "optical window", the region of the electromagnetic spectrum that allows wavelengths to pass largely unattenuated through the Earth's atmosphere. An example of this phenomenon is that clean air scatters blue light more than red wavelengths, and so the midday sky appears blue. The optical window is also referred to as the "visible window" because it overlaps the human visible response spectrum. The near infrared (NIR) window lies just out of the human vision, as well as the Medium Wavelength IR (MWIR) window, and the Long Wavelength or Far Infrared (LWIR or FIR) window, although other animals may experience them.
Learn about the energy the sun produces and how longer or shorter wavelengths of light gets to Earth and some get send back to space. Visible Spectrum is between 380nm to 700nm. -- Learn about: Wavelength, Light, Ultraviolet, Infrared, Visible Light, Nanometers and more.
An extra credit assignment for science...how beautiful...
Mr. Andersen describes visible light while discussing the electromagnetic spectrum. A simple description of the eye, optical illusions and lights are also included.

more ambient bass noise with the gsp on jack-rack. This is with the ampeg bass. I captured the projectM visuals with glc-capture, edited the capture with avi-demux and assembled the video with openshot.
Newton's prism experiments (part 1). When white light shines through a prism, the white light is broken apart into the colors of the visible light spectrum. Water vapor in the atmosphere can also break apart wavelengths creating a rainbow.

Microwaves, radio waves, x-rays and more are hiding, invisible, just beyond our perception. Lucianne Walkowicz shows us the waves we can't see.

Visible light is represented by only 1 inch on an electromagnetic scale of over 2,000 miles. (from "The Universe" series about Nebulas)
THIS MAN EXPLAINS THIS CONCEPT SOO WELL EVEN BETTER THAN THE LEGENDARY ERIC DOLLARD HERE IS THE LINK TO ERIC DOLLARD TALKING ON THIS CONCEPT IN HIS OWN WORDS HE LIKES TO CALL IT MATTER INSTEAD OF AETHER, MATTER ONLY EXISTS FROM LIGHT OR ELECTRONS GOING THRU PROTONS AND ETC AKA THRU THE AETHER. I AM PROBABLY THE ONLY ONE TO CONCLUDE THE OBVIOUS CONCLUSION AT LEAST OBVIOUS TO ME FROM GOD
This took FOREVER to finally finish but I did it! This was mentioned in a Hanwier Chronicles and someone on Tumblr mentioned that someone should write it and gosh dang if that shouldn't be me.
