WebScattering is a process, which conserves the total amount of energy, but the direction in which the radiation propagates may be altered. Absorption is a process that removes energy from the electromagnetic radiation field, and converts it to another form. Extinction (or attenuation)is the sum of scattering and absorption, so it represents total effect of … Rayleigh scattering is an important component of the scattering of optical signals in optical fibers. Silica fibers are glasses, disordered materials with microscopic variations of density and refractive index. These give rise to energy losses due to the scattered light, with the following coefficient: where n is the refraction index, p is the photoelastic coefficient of the glass, k is the Boltzmann c…
