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.

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 University wishes to appoint a Contractor or Contractors to supply a fully integrated, easy to operate, high resolution x-ray diffractometer for powder diffraction, residual stress, structure and texture analysis in standard and glancing angle modes.
Hence there is a reflection when the glancing angle satisfies Bragg's Law.
To be reflected, rather than absorbed, X rays must strike a mirror at a glancing angle, like a stone skipping across a pond.
