	Angle of incidence - Wikipedia, the free encyclopedia
		Angles of incidence of about 6° are common on most general aviation designs.
		It should not be confused with the angle of attack, which is the angle the wing chord presents to the airflow in flight.
		An angle of incidence is the angle between a beam incident on a surface and the line perpendicular to the surface at the point of incidence, called the normal.

	Angle of Incidence (Site not responding. Last check: 2007-10-21)
		The angle of incidence is the angle between the aircraft's longitudinal axis and the chord of the wing.
		The angle of incidence is the angle at which the wing is fixed to the aircraft's fuselage.
		It is the angle formed by the chord of the airfoil and the longitudinal axis of the aircraft.This longitudinal axis of the aircraft is the imaginary line drawn through the fuselage from the front of the aircraft to the rear of the aircraft.

	Critical angle - Wikipedia, the free encyclopedia
		In geometric optics, at a refractive boundary, the critical angle is the angle of incidence above which total internal reflection occurs.
		The angle of incidence is measured with respect to the normal at the refractive boundary.
		If the incident ray is precisely at the critical angle, the refracted ray is tangent to the boundary at the point of incidence.

		Angle of attack is one of the primary factors that determines amount of lift and drag produced by an airfoil.
		Angle of attack should not be confused with angle of incidence (blade pitch angle).
		Angle of incidence is the angle between the blade chord line and the plane of rotation of the rotor system.

		(These two angles are labeled with the Greek letter "theta" accompanied by a subscript; read as "theta-i" for angle of incidence and "theta-r" for angle of reflection.) The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.
		The diagram shows that the light reflects off the mirror in such a manner that the angle of incidence is equal to the angle of reflection.
		A ray of light is incident towards a plane mirror at an angle of 30-degrees with the mirror surface.

	The Critical Angle (Site not responding. Last check: 2007-10-21)
		So the critical angle is defined as the angle of incidence which provides an angle of refraction of 90-degrees.
		This equation for the critical angle can be used to predict the critical angle for any boundary, provided that the indices of refraction of the two materials on each side of the boundary are known.
		Suppose that the angle of incidence of a laser beam in water and heading towards air is adjusted to 50-degrees.

	Angle of incidence - RC Groups
		The angle of the fuselage to the direction of flight affects the drag of the fuselage but has little effect on the pitch trim unless the projected area of the fuselage is large and the angle of the fuselage to the direction of flight is quite large.
		These calculations are complicated by the down wash angle of the wing wake over the tail which affects the tail angle of attack and the speed of the flow over the tail being less than the airspeed because of wake effects.
		The trimmed airspeed and pitch attitude of a stable plane are determined by the decalage angle between the wing chord and horizontal tail chord.

	Oilfield Glossary: Term 'angle of incidence'
		The acute angle at which a raypath impinges upon a line normal to an interface, such as a seismic wave impinging upon strata.
		Normal incidence is the case in which the angle of incidence is zero, the wavefront is parallel to the surface and its raypath is perpendicular, or normal, to the interface.
		Snell's law describes the relationship between the angle of incidence and the angle of refraction of a wave.

	AVS Forum - Reflection energy v. angle of incidence
		With a perfect mirror, the reflected light energy is not a function of the angle of incidence.
		The phase angle is a function of the relative path lengths.
		The amount reflected vs. absorbed is dependent on a combination of the density and transmissivity per frequency and the angle of incidence.

	Numerical calibration of the angle of incidence in ellipsometers (Site not responding. Last check: 2007-10-21)
		Numerical calibration of the angle of incidence in ellipsometers
		The experimental error in the angle of incidence strongly affects the film optical constants and thickness sought from the ellipsometric data, particularly when the film is thinner than 200 Å.
		An error analysis shows that the angle of incidence can thus be determined with an uncertainty of a few hundredths of a degree from ellipsometers inducing the same order of angular errors.

	Controlling incidence angle (Site not responding. Last check: 2007-10-21)
		If the reflector in the subsurface is generally gentle and the lateral velocity change is small, the slanted wavefronts with constant ray parameters are enough to retrieve the angle-dependent reflectivity.
		is the stacked section obtained by synthesizing a plane wave with 10 degrees of incidence angle at 1200 m depth (Figure
		The image obtained by synthesizing a constant incidence angle is readily interpretable in terms of an angle-dependent reflectivity of the reflectors where the plane-wave is synthesized, since we can easily calculate the incidence angle to reflector from the angle of synthesized plane-wave and the dip of reflector.

	Angle of incidence question - RC Groups
		I have Great Planes laser incidence meter and it appears to me that it measures the chord from a point higher up on the leading edge than what the chord across the bottom of the wing would be.
		This is because the 90 degree angle bracket of the meter sets around the curved leading edge, raising the line being measured up 1/4 to 3/8 inch above the flat bottom projected line.
		It is generally done by presuming the flattish portion aft of the spar is the index for the angle the wing sits on the fuselage, for those planes where the true orientation isn't specified..

	Multiple-angle-of-incidence ellipsometry (Site not responding. Last check: 2007-10-21)
		When plane-polarized light is reflected from the surface of a material at some oblique angle of incidence, the reflected light is, in general, elliptically polarized.
		Thus, using an ellipsometer to determine the degree of ellipticity enables a measurement of material parameters.
		In this review, we will concentrate on ellipsometers in which the angle of incidence of light on the material is varied.
