Noun
the angle that a line makes with a line perpendicular to the surface at the point of incidence
Source: WordNetAnother calculation is made of the angle of incidence of light rays from the light source(s), and from these as well as the specified intensities of the light sources, the value of the pixel is calculated. Source: Internet
AirPower May 2002, p. 36. The angle of incidence of the delta wings could be reduced for greater stability and less drag at high speeds, and more weight carried, such as fuel. Source: Internet
But in the general case of reflection at a nonzero angle of incidence, no such generalization can be made. Source: Internet
Conversely, the apparent height approaches infinity as the angle of incidence (from below) increases, but even earlier, as the angle of total internal reflection is approached, albeit the image also fades from view as this limit is approached. Source: Internet
As the angle of incidence increases, the "escape" distance of one side of the beam will decrease, and more secondary electrons will be emitted. Source: Internet
But the angle of incidence equals the angle of reflection so the angle between the object ray and the normal must also increase by 20°. Source: Internet
