angle of incidence

n.
The angle formed by a ray or wave incident on a surface and a line perpendicular to the surface at the point of incidence.

angle of incidence

n
1. (General Physics) the angle that a line or beam of radiation makes with the normal to the surface at the point of incidence
2. (Aeronautics) another name for angle of attack
3. (Aeronautics) Also called: rigging angle of incidence the angle between the chord line of an aircraft wing or tailplane and the aircraft's longitudinal axis

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.
