Light Rays The angle the light rays from the sun make with the surface of the earth is called the angle of incidence. When there is a large angle of incidence, the light rays are spread out over a large area. The strength of the incoming beam is weakened as far as a small portion of the surface is concerned. When the light bears straight down on a surface, it isn't spread out at all and the surface feels the full intensity of the beam
