Resumo: We study the bending of light caused by a static gravitational field generated by a localized material source in the context of quadratic gravity. Our calculation shows that for light rays passing close to the Sun the deflection $ lies in the interval 0 < φ < 1.75″. A tree-level approach to the same issue tells us that the vacuum concerning quadratic gravity is a dispersive medium. Now φ is energy dependent and ranges from 0- to 1.75- arcsec.
