The Many Uses of Visible Light
New uses for visible light are discovered every day.
2. Visible light can be used to move energy and data with fiber optic cables. Light travels through the cables much in the same way electricity travels through copper wires, so it can be used to replace electricity.
3. Visible light can be used to check for information, like in bar code scanners. Bar code scanners work by illuminating bar codes with red light and interpreting the result as the ID of an item, like in a grocery store.
4. Visible light can be used to capture images, like in digital cameras. When you open the shutter of a digital camera, light floods the inside of the camera and is detected by an electronic device that also captures and stores the image.
Our eyes capture light and use it for vision.
Flashlights illuminate an area with light, allowing it to be seen.
Bar code scanners can check bar codes for information to identify a product.
Wavelength and Frequency
The technology works because of its use of fiber-optic cables, which harvest energy from the light as it travels through them.
This technology impacts the world by harvesting energy more efficiently, less harmfully to the environment, and in a more aesthetically pleasing way. It no longer takes so much space to gather electricity, it no longer hurts the environment so much, or even at all, and it no longer looks ugly as you do it.
Research began for the technology in November 2009, but even today new advances and modifications are being made, making the technology as new as ever with each passing year.
