The field oscillates in the x-y plane, along the page, with the wave propagating in the z direction, perpendicular to the page. The first two diagrams below trace the electric field vector over a complete cycle for linear polarization at two different orientations; these are each considered a distinct state of polarization . Note that the linear polarization at 45° can also be viewed as the addition of a horizontally linearly polarized wave and a vertically polarized wave of the same amplitude in the same phase. Light or other electromagnetic radiation from many sources, such as the sun, flames, and incandescent lamps, consists of short wave trains with an equal mixture of polarizations; this is called unpolarized light. Polarized light can be produced by passing unpolarized light through a polarizer, which allows waves of only one polarization to pass through. The most common optical materials do not affect the polarization of light, however, some materials—those that exhibit birefringence, dichroism, or optical activity—affect light differently depending on its polarization.

Kitchen islands or counters, in particular, are ideal surfaces above which linear hanging light fixtures makes a good deal of sense. By providing broad and practical illumination for kitchen-related tasks, and also acting as visual bookends to the horizontal surface areas below, linear hanging kitchen lights imbue kitchens with a clean, finished appearance. LED linear lighting distributes light evenly to help avoid glare, which is another advantage over traditional linear fluorescent lights. Both linear and strip lights are suitable for use in a range of directional applications, offering style and functionality for any lighting design. This allows the user to buy the length of strip required for the application. While linear lighting can, of course, be linked, individual linear luminaires are usually sold in predetermined lengths. Depending on the application, an effective alternative to linear lighting may be strip lighting. Surface-mounted lights are frequently used in office environments.

With regards to IP rating , many products are around IP20 however you will find luminaires on the market which are IP65 rated . Size can also vary greatly with linear lighting; you can have single pendants of linear lighting or continuous runs of over 50m. These could be large enough to illuminate a room or small linear lighting for ambience or task lighting such as under-cabinet lighting. General purpose linear light bulbs are straight, tube-shaped bulbs with bases on both ends. fixtures lend themselves to the modern dining room and kitchen thanks to their horizontal length and bright downlighting. Over the dining table, you’ll love the widespread light a rectangular chandelier can offer and it’s also the ideal option to hang over a kitchen island when you prefer light coming from one source versus many .

Polarized 3D glasses with suitable polarizing filters ensure that each eye receives only the intended image. Historically such systems used linear polarization encoding because it was inexpensive and offered good separation. However circular polarization makes separation of the two images insensitive to tilting of the head, and is widely used in 3-D movie exhibition today, such as the system from RealD. In the important special case of reflection at normal incidence there is no particular s or p polarization. Both the x and y polarization components are reflected identically, and therefore the polarization of the reflected wave is identical to that of the incident wave. However, in the case of circular polarization, the handedness of the polarization state is thereby reversed, since by convention this is specified relative to the direction of propagation. The circular rotation of the electric field around the x-y axes called “right-handed” for a wave in the +z direction is “left-handed” for a wave in the -z direction.

If one were to plot the electric field vector over one cycle of oscillation, an ellipse would generally be obtained, as is shown in the figure, corresponding to a particular state of elliptical polarization. Note that linear polarization and circular polarization can be seen as special cases of elliptical polarization. Now if one were to introduce a phase shift in between those horizontal and vertical polarization components, one would generally obtain elliptical polarization as is shown in the third figure. When the phase shift is exactly ±90°, then circular polarization is produced . Thus is circular polarization created in practice, starting with linearly polarized light and employing a quarter-wave plate to introduce such a phase shift. The result of two such phase-shifted components in causing a rotating electric field vector is depicted in the animation on the right. Note that circular or elliptical polarization can involve either a clockwise or counterclockwise rotation of the field. These correspond to distinct polarization states, such as the two circular polarizations shown above.

The circling dot will trace out a helix with the displacement toward our viewing left, leading the vertical displacement. The nature of circular polarization and its relationship to other polarizations is often understood by thinking of the electric field as being divided into two components that are perpendicular to each other. The vertical component and its corresponding plane are illustrated in blue, while the horizontal component and its corresponding plane are illustrated in green. Notice that the rightward horizontal component leads the vertical component by one quarter of a wavelength, a 90° phase difference. It is this quadrature phase relationship that creates the helix and causes the points of maximum magnitude of the vertical component to correspond with the points of zero magnitude of the horizontal component, and vice versa. The result of this alignment are select vectors, corresponding to the helix, which exactly match the maxima of the vertical and horizontal components. Circular polarization occurs when the two orthogonal electric field component vectors are of equal magnitude and are out of phase by exactly 90°, or one-quarter wavelength. Circular polarization is a limiting case of elliptical polarization. The other special case is the easier-to-understand linear polarization.

along with 3 planar projections and a deformation surface of total electric field. Moreover, one can use as basis functions any pair of orthogonal polarization states, not just linear polarizations. For instance, choosing right and left circular polarizations as basis functions simplifies the solution of problems involving circular birefringence or circular dichroism. For longitudinal waves such as sound waves in fluids, the direction of oscillation is by definition along the direction of travel, so the issue of polarization is not normally even mentioned. On the other hand, sound waves in a bulk solid can be transverse as well as longitudinal, for a total of three polarization components. The differential propagation of transverse and longitudinal polarizations is important in seismology.

In 1911, Albert Abraham Michelson discovered that light reflected from the golden scarab beetle Chrysina resplendens is preferentially left-polarized. Since then, circular polarization has been measured in several other scarab beetles such as Chrysina gloriosa, as well as some crustaceans such as the mantis shrimp. In these cases, the underlying mechanism is the molecular-level helicity of the chitinous cuticle. The rose chafer’s external surface reflects almost exclusively left-circularly polarized light. Polarization is a manifestation of the spin angular momentum of light. As stated earlier, there is significant confusion with regards to these two conventions.
