VISIBLE LIGHT DESCRIPTION • Generally, visible light is defined as the wavelengths that are visible to most human eyes. • 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. • Visible light is one way energy uses to get around. Light waves are the result of vibrations of electric and magnetic fields, and are thus a form of electromagnetic radiation. • Light and all other electromagnetic waves travel at the enormous speed of 186, 000 miles per second or 300, 000 kilometers per second in a vacuum.

FACTS ABOUT THIS LIGHTSPECTRUM • WElectromagnetic radiation that is visible to the human eye and is responsible for the sense of light. • The benefits of visible light waves is that it gives off light for us to see and notice things around us. The dangers is that too much light can damage the retina of the eye. • The occupational exposure limits for this type of radiation would be when the visible light causes damage to hat your eyes pick up and turn into a picture in your brain is all caused by visible light waves. your eyes or burning of the skin. • Visible light communication is a data communications variant which uses visible lightbetween 400 and 800 THz. VLC is a subset of optical wireless communications technologies. • A prism can break white light up into the visible lightspectrum. Visible light is a form of electromagnetic (EM) radiation, as are radio waves, infrared radiation, ultraviolet radiation, X-rays and microwaves.
