angle of incidence

[′aŋ·gəl əv ′in·sə·dəns]
(optics)
The angle formed by a ray arriving at a surface and the perpendicular to that surface at the point of arrival. Also known as incidence angle.

Angle of incidence

In terms of solar energy, the angle that the sun’s rays make with an imaginary line perpendicular to a surface. The angle of incidence determines the intensity of the energy that any surface experiences.

Angle of incidence is the angle between the fuselage reference line and the wing chord.
angle of incidence
Incident rays on a surface. Two ways of measuring angle of incidence.
i. The acute angle formed between the chord line of an airfoil and the longitudinal axis of the aircraft on which it is mounted. This is the angle at which the airfoil is attached to an aircraft fuselage when the aircraft is in rigging position. Unlike the angle of attack, the angle of incidence is a fixed entity.
ii. The angle at which a ray of energy impinges upon a surface, usually measured between the direction of propagation of the energy and the perpendicular to the surface at the point of impingement, or incidence. In some cases involving radio waves, the angle of incidence is measured relative to the surface.

The interception of the beam radiation by fabric surfaces is dependent on the angle of incidence, [theta].
The measured drop in intensity, for a given angle of incidence, is related to the inner slope of the scratch contour as well as the roughness (or scattering) of the material inside the scratch.
In particular, one notes the increase in the drag with the increase in the angle of incidence.
So, accordingly, the value of the angle of incidence of electrons on the barrier could be obtained from boundary conditions along the y-direction as we will see below.
While keeping the flow parameters to the values presented earlier, the angle of incidence has been varied from 0 to 20 degrees by 5-degree increments.

The photodiodes are oriented relative to the entrance aperture so that the principal ray of incoming radiation strikes each diode once at a 45[degrees] angle of incidence and then reflects from the concave mirror back again onto the photodiodes in reverse order.
Most of the experimental data were derived from specular reflectivity data; thus, the intensity of the reflected signal was measured as a function of the angle of incidence, while the incident and reflection angles were maintained as equal.
If the angle of incidence on the target is over 45 [degrees] (angle between the surface and the beam is less than 45 [degrees]), the result is that blind areas cannot be implanted well.
