Light absorption rate is affected mostly by the _____ of the light and the _____ .

** is the answer A,B,C OR D **

A. wavelength

B. core diameter, transmission mode

C. characteristics of the glass

D. refractive index, temperature of the glass

Solution

Apsorption rate depends on the wavelength of incident ligh, because substance(material) does not absorve all the wave length of incident light, it absorve only those wavelength of light that brings the electron from ground state to excited state.

absorption rate depends on the complex permittivity of the material, as complex permivity provides the attenuation to light waves and hence absorption increases.

Absorption rate also depends on the depth of material in which light travels, if depth is more then absorption is more.
