properties :-
Visible lightis produced by vibrations androtationsofatomsand molecules, as well as by electronic transitions within atoms and molecules. We say the atoms and molecules are excited when they absorb and relax when they emit through electronic transitions.*.This figure shows the visible part ofthespectrum, together with the colors associated with particular purewavelengths. Red light has the lowestfrequenciesand longest wavelengths, while violet has the highest frequencies and shortest wavelengths.*.Colors that can be produced by visible light of a narrow band of wavelengths are called purespectral colors. They can be delineated roughly in wavelength as: violet (380-450 nm), blue (450-495 nm), green (495-570 nm), yellow (570-590 nm), orange (590-620 nm), and red (620 to 750 nm).*.Visible wavelengths pass through theoptical window, the Earth's atmosphere allows this region of theelectromagnetic spectrum to pass through largely unattenuated (see opacity plot in.*.The portion of the EM spectrum used by photosynthesic organisms is called the photosynthetically active region (PAR) and corresponds to solarradiationbetween 400 and 700 nm, substantially overlapping with the range of human vision.
uses are :-
*.seeing the world*.signaling*.all the science that occurs using lasers emitting in the visible spectrum*.UV/Vis spectroscopy (spectroscopy that usesUV and Visible light)*.Astronomy*.Military applications*.growing food (photosynthesis means plant growth, but also greenhouse effect in greenhouses)
