Interaction of light with nanoparticles led to extensive knowledge about electromagnetic processes which is fundamental. One of the light effects on the metal nanowires, is the changing of the light polarization . The aimof this research is to study size effects and the surrounding environment properties of nanowires on the degreeof polarization of scattered light. Gold and silver metallic nanoparticles due to wide spread use of properties wereselected herein. Simulated polarization of scattered light with a FORTRAN program was obtained. Parameters affecting the intensity and degree of polarization of scattered light radius, refractive index and the wavelength of incident light was made nanowire. This research was based on theory as well as simulation method. Nanowirelengths, nanowire interaction with the surrounding dielectric environment were changed polarization of the surrounding molecular nanowires. It has been concluded that silver and gold had the same polarization pattern
