A quantum model for optical conductivity that treats light as a particle is presented. Based on this assumption, the optical characteristics of the material are calculated and compared to experimental findings. The band gap energy of a material changes with frequency and refractive index. We provided an equation of the line extrapolated in the Tauc plot. The obtained formula for optical conductivity reveals that the band tailing parameter in the Tauc formula is dependent on the speed of light, the Planck constant, and the material's refractive index. The determination of this constant helps establish the value of the band. The values of this constant are found to be consistent with various experimental results. Two electric conductivities distinguishing Abraham and Minkoswi's light momentum relationship inside materials are proposed.
