For Angle of Incidence we have terms and definitions in 7 topics. The topics are Airfoil, Aviation, Climatology, Energy, Photography, Physical Geography and Solar Energy.

Angle Of Incidence (Airfoil)

Angle between the reference axis (x-axis) of an airfoil and the reference axis of the aircraft (e.g. fuselage center line). Constant, built into the aircraft.

Angle Of Incidence (Aviation)

The angle at which an airfoil is normally fixed in relation to the longitudinal axis of an aircraft.

Angle Of Incidence (Climatology)

The angle at which a ray of light (or radiation) strikes a surface. It is measured between the incoming ray and a perpendicular to the surface at the point of incidence (i.e., where the ray strikes).

Angle Of Incidence (Energy)

The angle that the sun's rays make with a line perpendicular to a surface. The angle of incidence determines the percentage of direct sunshine intercepted by a surface.

Angle Of Incidence (Photography)

When light strikes a surface it forms an angle with an imaginary line known as the : normal, which is perpendicular to the surface. The angle created between the incident ray and the normal is referred to as the angle of incidence.

Angle Of Incidence (Physical Geography)

Angle at which the sun's rays or insolation strike the Earth's surface. If the sun is positioned directly over head or 90° from the horizon, the incoming insolation strikes the surface of the Earth at right angles and is most intense.

Angle Of Incidence (Solar Energy)

The angle that a ray of sun makes with a line perpendicular to the surface. For example, a surface that directly faces the sun has a solar angle of incidence of zero, but if the surface is parallel to the sun (for example, sunrise striking a horizontal rooftop), the angle of incidence is 90°.
