We analyse reflection of light with taking into account the influence of gravitation field (GF). It is shown that the GF of spherically symmetric mass should cause reflection of electromagnetic wave. The reflection coefficient is estimated to be 0.198 in case of a nor-mal incidence of electromagnetic wave at a black hole. This should lead to appearance of a halo around black holes. Oblique incidence and the absorption effect are demonstrated to give rise to increasing reflection coefficient. They could also yield elliptical polarization of the reflected light.
