Electromagnetic radiation that has a wavelength in the range from about 4,000 (violet) to about 7,700 (red) angstroms and may be perceived by the normal unaided human eye.
Optical constants and dielectric constants of normal cesium oxide thin films are related to wavelength of incident light and cesium impurity contained.
