## an′gle of in′cidence

n.
1. Also called incidence. the angle that a ray, as of light, makes with a normal to a surface at the point where the ray meets the surface.
2. (on an airplane) the angle, usu. fixed, between a wing or tail root chord and the axis of the fuselage.

## angle of incidence

The angle formed by a ray or wave, as of light or sound, striking a surface and a line perpendicular to the surface at the point of impact. See more at wave.

The value of distortion at a given image point is a function of incoming ray angle of incidence.
The idea of light travelling through a Fiber is first the light gets injected into the Fiber and strike the core to cladding interface at an angle greater than the critical angle, reflects back into core, since the angle of incidence and reflection are equal.
