The radiation detected by human eyes is named the visible spectrum. Visible radiation also known as light is the only portion of the spectrum that can be perceived as colors. These wavelengths span a very narrow portion of the spectrum, ranging from approximately 400 to 700 nm (see illustration below).

Here are the wavelengths of the basic colors:

Red ------> 780 to 622 nm
Orange --> 622 to 597 nm
Yellow ----> 597 to 577 nm
Green ----> 577 to 492 nm
Blue -------> 492 to 455 nm
Violet -----> 455 to 390 nm

Note: 1 nm (nanometer) = 10^(-9) m
