Recently, research interest in the field of nanotechnology has increased. This thesis studies the effect of stress on the optical properties of graphene mono-sheet with two types of incident light; polarized light and unpolarized light. We used in this thesis the density functional theory, where we multiply the original length of the graphene mono-sheet by the stress factor. Then we get results for five optical properties of graphene: absorption, conductivity, reflectivity, dielectric function, and refractive index. Through these results, we found that there is a significant effect of the different stress factors on these five properties
