When a polarizing sheet is placed in the path of light, only electric field components of the light parallel to the sheet’s polarizing direction are transmitted by the sheet; components perpendicular to the polarizing direction are absorbed. The light that emerges from a polarizing sheet is polarized parallel to the polarizing direction of the sheet.
American spy agencies have assessed that the Kremlin favors former President Donald J. Trump, seeing him as skeptical of U.S. support for Ukraine.
Due to high demand and limited spots there is a waiting list. You will be notified when your spot in the Trial Session is available.
If the original light is initially polarized, the transmitted intensity depends on the angle (θ )between the polarization direction of the original light and the polarizing direction of the sheet:

• If the original light is initially unpolarized, the transmitted intensity I is half the original intensity. If the original light is initially polarized, the transmitted intensity depends on the angle θ.

Dimitri K. Simes, who was an adviser to Donald J. Trump’s first campaign, and his wife, Anastasia Simes, are accused of violating U.S. sanctions.

• There is linear polarization (confined to a single plane) and circular polarization (two linear components that are perpendicular to each other.)

El FBI allanó los domicilios de dos conocidos comentaristas de canales de televisión estatales rusos como parte de un esfuerzo por desmontar los intentos de influir en las elecciones de noviembre.
The festival canceled the screenings of “Russians at War,” which has been criticized as Kremlin propaganda. The filmmaker has said it is an antiwar film.

Scientists fighting the spread of infectious diseases on the continent have been targeted online by pro-Russian activists, part of an effort to spread fear and mistrust of the West.
Polarization can occur in two forms. Linear polarization where the electric field of light is confined to a single plane along the direction of propagation. Or circular polarization, where the electric field of the light consists of two linear components that are perpendicular to each other, equal in amplitude but have a phase difference of π/2. The resulting electric field rotates in a circle around the direction of propagation and, depending on the rotation direction, is called left- or right-hand circularly polarized light.
Sanctions announced on Friday are an effort to undercut RT by making it difficult for the network to conduct global business in dollars.
The head of the department’s national security division amplified warnings that other countries were seeking to sway the outcome in November, including Russia’s efforts to help Donald Trump.
Social media companies may try to ban RT, the Russian state media broadcaster. But the network has proved in the past to be a wily adversary when confronted with efforts to silence it.
Light waves from common sources (sunlight, halogen lighting, LED spotlights, and incandescent bulbs) are unpolarized, or polarized randomly.
Las empresas de redes sociales pueden intentar prohibir RT, la emisora estatal rusa, pero la red de medios ya ha demostrado ser un adversario astuto cuando se enfrenta a los esfuerzos por silenciarla.
Electromagnetic waves are polarized if their electric field vectors are all in a single plane (linear polarization), or in 2 plans perpendicular to each other, equal in amplitude, but have a phase difference of π/2 (circular polarization).

The owner of Facebook and Instagram said it would bar Russian media outlets including RT, while YouTube is removing channels it had already blocked.
