Of a wave propagating in a material medium, a phenomenon in which the direction, frequency, or polarization of the wave is changed when the wave encounters discontinuities in the medium, or interacts with the material at the atomic or molecular level.
A property of glass that causes light to deflect from the fiber and contribute to losses (intrinsic attenuation).
(shuttle, criss-cross,) a type of shell of shells. After a short delay from the shell break, the shell inserts that are thrown out project only two stars in opposite directions. The stars travel at a great speed making this a dramatic effect. Example
The process in which a wave or beam of particles is diffused or deflected by collisions with particles of the medium which it traverses.
A property of glass that causes light to deflect from the fiber and contributes to optical attenuation.
Subject: The Earth The process by which small particles in the atmosphere deflect radiation from its path into different directions.[ Pics List
The dispersal of a beam of particles or of radiation into a range of directions as a result of physical interactions.
Change in direction of light ray due to heterogeneity (imperfections) in material. When ray hits an imperfection, it is reradiated in a direction different from that of the original ray.
The reflection of light from a rough surface in many directions with each individual photon following the law of reflection. This is also known as diffuse reflection.
A process that changes a particle's trajectory. Scattering is caused by particle collisions with atoms, nuclei and other particles or by interactions with electric or magnetic fields. If there is no change in the total kinetic energy of the system, the process is called elastic scattering. If the total kinetic energy changes due to a change in internal energy, the process is called inelastic scattering. See also backscattering.
Scattering occurs when light collides with individual atoms in the glass. This is one of several causes of attenuation.
interaction of radiation with matter where its direction is changed, but the total energy and wavelength remain unaltered Streuung
the physical process in which particles are deflected haphazardly as a result of collisions
a light shower that falls in some locations and not others nearby
The loss of signal power (light) from the fiber core caused by impurities or changes in the index of refraction of the fiber.
The redirection of photons by molecules, aerosols, or other particles in the air.
The change of direction of light after striking small particles that causes loss in optical fibers.
The multiple reflection of EM radiation off surfaces or particles. This leads to a decrease in the energy being transmitted.
(1) The process by which small particles suspended in a medium of a different index of refraction diffuse a portion of the incident radiation in all directions, eg, atmospheric scattering. (2) The process by which a rough surface re-radiates electromagnetic radiation incident upon it.
The dispersal of energy that occurs when light interacts with particles in the atmosphere.
A property of glass which causes light to deflect from the fiber & contributes to losses.
Multiple reflection of electromagnetic waves by gases or particles in the atmosphere.
the process by which small particles are forced to change their direction of motion
Redirection of light reflecting off a surface or through an object. See diffuse.
An interaction of a light wave with an object that causes the light to be redirected.
The bending of light rays as they bounce off very small objects.
A second cause of attenuation. Scattering occurs when light collides with individual atoms in the glass.
The amount of light that is reflected and refracted away from a particle. The measurement is widely used to estimate overall concentrations of particles suspended in water, and can also be used to look at specific material properties.
The process by which a material interacts with and redirects incident radiation (in any given direction).
bouncing of light in another direction when it hits a molecule in the atmosphere
Loss of signal power caused by fiber impurities or changes in the fiber's index of refraction.
The change in the paths of photons without absorption or change in wavelength.
The random redirection of RF energy from irregular conducting surfaces.
In a broad sense, the process by which matter is excited to radiate by an external source of electromagnetic radiation, as distinguished from emission of radiation by matter, which occurs even in the absence of such a source. By this definition, reflection, refraction, and even diffraction of electromagnetic waves are subsumed under scattering. Sometimes scattering is applied in a restricted sense to that radiation not accounted for by the laws of specular reflection and refraction, which are approximate because matter is not continuous on all scales. Often the term scattered radiation is applied to that radiation observed in directions other than that of the source and may also be applied to acoustic and other waves. If there is no change in frequency between the incident and scattered radiation, the scattering is sometimes said to be elastic; the converse is inelastic. Scattering is also applied to any interaction between particles that results in a change in direction. See multiple scattering, Mie theory, Rayleigh's scattering law. Born, M., and E. Wolf, 1965: Principles of Optics, 3d rev. ed., 98–108. Doyle, W. T., 1958: Am. J. Phys., 53, 463–468.
The process by which small particles suspended in the air diffuse a portion of the incident radiation in all directions. This is a primary reason for colors, such as blue skies, rainbows, and orange sunsets. When working with radars, this often refers to the more or less random changes in direction of radio energy.
a property of glass that causes light to deflect from optical fiber. It contributes to attenuation.
Causing of lightwave signal loss in optical fiber transmission; diffusion of a light beam caused by microscopic variations in the material density of the transmission medium.
The change of direction of light rays or photons after striking small particles. It may also be regarded as the diffusion of a light beam caused by the inhomogeneity of the transmitting material.
Scattering is a general physical process whereby some forms of radiation, such as light or moving particles, for example, are forced to deviate from a straight trajectory by one or more localized non-uniformities in the medium through which it passes. It can also be seen with some sound phenomena. In conventional use, this also includes deviation of reflected radiation from the angle predicted by the law of reflection.
Optics scattering deals with electromagnetic radiation scattering, absorption, and extiction by particles, molecules and surfaces. Both single scattering and multiple scattering (i.e. radiative transfer) are considered in this category.
