Investigation of Polarisation

Polarization studies [IMAGE] Natural light (and most other lighting) transmits light waves that oscillate in all different planes where the electric field vector is related to the transmission direction. When these electric fields are confined in a single plane by filtering, light is called polarization because all light waves oscillate in the same plane. When unpolarized light passes through a Polaroid filter, its brightness is only half that of the previous one, and all waves propagate in the same plane.

The light as a wave can be directed in any direction, but the polarized light is oriented in the same direction. The lens you wear to see a 3D movie is polarized - the left lens is polarized in one direction and the right lens is polarized in the opposite direction perpendicular to it. Project the movie (twice) using a polarizing filter matching the polarization of the lens. This is more explanation. All the plastics used in the above video and photograph are placed in front of the monitor of the polarized laptop computer. If the plastic is stressed (it is itself stretched or torn or it is pressurized during manufacturing processes such as injection molding), then those areas will not reflect the polarization of the light passing through it Change the color to make it visible through 3D glasses.

In 1845, Michael Faraday discovered that when light travels in the direction of the light field in the presence of a transparent dielectric, we discover that the plane of polarization of linearly polarized light rotates and this effect is called Faraday rotation. This is the first evidence on light and electromagnetism. In 1846, he speculated that the light might be some sort of interference propagated along the field lines. In 1847 Faraday proposed that light is a type of high frequency electromagnetic vibration that can be transmitted without a medium like ether.

In classical electrodynamics, light is considered to be an electromagnetic wave, which is described by Maxwell's equation. The light wave incident on the material causes polarization oscillation (or oscillation of electrons in the metal) within a single atom so that each particle emits small secondary waves in all directions like a dipole antenna. According to Huygens-Fresnel's principle, these waves sum together specular reflection and refraction. In the case of a dielectric such as glass, the electric field of light acts on the electrons in the material, the moving electrons create an electric field and become a new radiator. Refraction light in the glass is a combination of electron forward light and incident light. Reflected light is a combination of backward radiation of all electrons
