  2. Angle of incidence (optics) - Wikipedia

    en.wikipedia.org/wiki/Angle_of_incidence_(optics)

    The angle of incidence at which light is first totally internally reflected is known as the critical angle. The angle of reflection and angle of refraction are other angles related to beams. In computer graphics and geography , the angle of incidence is also known as the illumination angle of a surface with a light source, such as the Earth 's ...

  3. Snell's law - Wikipedia

    en.wikipedia.org/wiki/Snell's_law

    The largest possible angle of incidence which still results in a refracted ray is called the critical angle; in this case the refracted ray travels along the boundary between the two media. Refraction of light at the interface between two media. For example, consider a ray of light moving from water to air with an angle of incidence of 50°.

  4. YouTube Kids - Wikipedia

    en.wikipedia.org/wiki/YouTube_Kids

    YouTube Kids has faced criticism from advocacy groups, particularly the Fairplay Organization, for concerns surrounding the app's use of commercial advertising, as well as algorithmic suggestions of videos that may be inappropriate for the app's target audience, as the app has been associated with a controversy surrounding disturbing or violent ...

  5. Ellipsometry - Wikipedia

    en.wikipedia.org/wiki/Ellipsometry

    Ellipsometry is a specular optical technique (the angle of incidence equals the angle of reflection). The incident and the reflected beam span the plane of incidence. Light which is polarized parallel to this plane is named p-polarized. A polarization direction perpendicular is called s-polarized (s-polarised), accordingly.

  6. Plane of incidence - Wikipedia

    en.wikipedia.org/wiki/Plane_of_incidence

    The plane of incidence is defined by the incoming radiation's propagation vector and the normal vector of the surface. In describing reflection and refraction in optics, the plane of incidence (also called the incidence plane or the meridional plane [citation needed]) is the plane which contains the surface normal and the propagation vector of the incoming radiation. [1]

  7. Angle of incidence - Wikipedia

    en.wikipedia.org/wiki/Angle_of_incidence

    Angle of incidence is a measure of deviation of something from "straight on" and may refer to: Angle of incidence (aerodynamics), angle between a wing chord and the longitudinal axis, as distinct from angle of attack, which is relative to the airflow; Angle of incidence (optics), describing the approach of a ray to a surface

  8. Specular reflection - Wikipedia

    en.wikipedia.org/wiki/Specular_reflection

    The law of reflection states that the angle of reflection of a ray equals the angle of incidence, and that the incident direction, the surface normal, and the reflected direction are coplanar. When the light is incident perpendicularly to the surface, it is reflected straight back in the source direction.

  9. Plane mirror - Wikipedia

    en.wikipedia.org/wiki/Plane_mirror

    The angle of the incidence is the angle between the incident ray and the surface normal (an imaginary line perpendicular to the surface). Therefore, the angle of reflection is the angle between the reflected ray and the normal and a collimated beam of light does not spread out after reflection from a plane mirror, except for diffraction effects.
