When unpolarized light passes through a polarizer crystal, it becomes polarized in one direction. This polarized light then passes through the second crystal. If the two crystals are arranged parallel to each other, they will have a similar polarization axis, allowing the light to pass through. If the second crystal is rotated slightly, it will act as a polarizer and block some of the light, demonstrating the effect of polarization.
When light passes through a parallel arrangement of crystals, such as a polarizer-analyzer pair, the crystals filter the light waves based on their orientation. If the crystals are aligned parallel to each other, they allow light waves oscillating in a single plane (polarized light) to pass through while blocking the waves oscillating in other planes. This demonstrates the polarization of light, as only light waves vibrating in a specific direction can transmit through the arrangement.
There are 3240 arrangements.
Longitudinal waves do not exhibit polarization, which is a characteristic of transverse waves. Polarization refers to the orientation of the oscillations of the wave with respect to its direction of propagation. Since longitudinal waves have their oscillations parallel to the direction of propagation, they cannot exhibit polarization.

The double-headed arrows on polarizers and analyzers represent the direction of polarization that they allow to pass through their material. It indicates that light with polarization parallel to the arrow direction can pass through, while light with perpendicular polarization is blocked.
The states of polarization refer to linear, circular, and elliptical polarizations of light. In linear polarization, the electric field oscillates in a single plane. In circular polarization, the electric field rotates in a circular pattern. Elliptical polarization is a combination of linear and circular polarizations.
When two polaroid filters are held with their polarization axes at right angles to each other, no light is transmitted as the filters block all light waves aligned with their polarization axes. When their axes are parallel, the maximum amount of light is transmitted because all light waves can pass through without being blocked.

Co-polarization refers to the arrangement where the electric field vectors of two waves are parallel to each other. In radar and remote sensing, co-polarization is used to describe the same polarization of the transmitted and received signals. This helps in maximizing the signal strength and reducing interference from noise and other sources.
The two types of netted venation arrangements are pinnate venation, where the veins run parallel to each other along the midrib of the leaf, and palmate venation, where the veins radiate outward from a single point at the base of the leaf.
It centered of course around the 38th parallel as the division lie or border negotiated thru interminal cease fires and negotiating.
