INTRODUCTION
THE VISIBLE SPECTRUM
When white light passes through a prism, it is
separated into its constituent colors: the red, orange,
yellow, green, blue, indigo and violet. These colors
do not distinctly separate but they continuously
change from red to violet. Red color has the longest
wavelength from among these colors and violet has
the shortest
VISIBLE
SPECTRUM
The visible spectrum is the band 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). The optical spectrum is
sometimes considered to be the same as the
visible spectrum, but some authors define the
term more broadly, to include the ultraviolet
and infrared parts of the electromagnetic
spectrum as well.
