In electrodynamics, circular polarization of an electromagnetic wave is a polarization state in which, at each point, the electromagnetic field of the wave has a constant magnitude and is rotating at a constant rate in a plane perpendicular to the direction of the wave. In electrodynamics, the strength and direction of an electric field is ...
Cognitive distortion. A cognitive distortion is a thought that causes a person to perceive reality inaccurately due to being exaggerated or irrational. Cognitive distortions are involved in the onset or perpetuation of psychopathological states, such as depression and anxiety. [ 1]
Group polarization. In social psychology, group polarization refers to the tendency for a group to make decisions that are more extreme than the initial inclination of its members. These more extreme decisions are towards greater risk if individuals' initial tendencies are to be risky and towards greater caution if individuals' initial ...
Devices that block nearly all of the radiation in one mode are known as polarizing filters or simply "polarizers". This corresponds to g 2 =0 in the above representation of the Jones matrix. The output of an ideal polarizer is a specific polarization state (usually linear polarization) with an amplitude equal to the input wave's original ...
Polarizability. Polarizability usually refers to the tendency of matter, when subjected to an electric field, to acquire an electric dipole moment in proportion to that applied field. It is a property of particles with an electric charge. When subject to an electric field, the negatively charged electrons and positively charged atomic nuclei ...
Hindustani, also known as Hindi-Urdu, like all Indo-Aryan languages, has a core base of Sanskrit -derived vocabulary, which it gained through Prakrit. [ 1] As such the standardized registers of the Hindustani language (Hindi-Urdu) share a common vocabulary, especially on the colloquial level. [ 2] However, in formal contexts, Modern Standard ...
Polarizers are used in many optical techniques and instruments. Polarizers find applications in photography and LCD technology. In photography, a polarizing filter can be used to filter out reflections. The common types of polarizers are linear polarizers and circular polarizers.
The meaning of the butterfly Yeo included the image of a monarch butterfly in his portrait to illustrate Charles’ evolving role in recent years, he told the BBC.
