27 / 76 page  22 Application Notes—Photoconductive Cells APPLICATION NOTE #1 Light - Some Physical Basics Light is produced by the release of energy from the atoms of a material when they are excited by heat, chemical reaction or other means. Light travels through space in the form of an electromagnetic wave. A consequence of this wave-like nature is that each “color” can be completely defined by specifying its unique wavelength. The wavelength is defined as the distance a wave travels in one cycle. Since the wavelengths of light are very short they are normally measured in nanometers, one nanometer being equal to 1 x 10-9 meters. The spectral response of PerkinElmer’s photoconductors are specified by lots of relative response versus wavelength (color) for various material types.
