angle of incidence

• In angle of incidence

  …angle of incidence equals the angle of reflection. The reflected ray is always in the plane defined by the incident ray and the normal to the surface. The law of reflection can be used to understand the images produced by plane and curved mirrors. Reflection at rough, or irregular, boundaries…

optical fibers

• In telecommunications media: Optical fibres

  Different reflection angles within the fibre core create different propagation paths for the light rays. Rays that travel nearest to the axis of the core propagate by what is called the zeroth order mode; other light rays propagate by higher-order modes. It is the simultaneous presence of…

  …wave and a perpendicular (angle of reflection). Reflection at rough, or irregular, boundaries is diffuse. The reflectivity of a surface material is the fraction of energy of the oncoming wave that is reflected by it. See also total internal reflection.
