If the magnitude of light vectors changes periodically during rotation,the tip of vectors traces the ellipse and the light is said to be elliptically polarized light.
Polarization by reflection: When the ordinary light is incident on the transparent media like water and glass at polarizing angle the ray of light after the reflection become s plane polarized lightbecause that every vibration of the electric vector can be resolved into parallel and perpendicular components to the plane. The angle of incidence at which the intensity of the reflected light is completely polarized is a polarizing angle.
Polarization by selective absorption : Polarization can be produced by using the material like Polaroid and doubly refracting crystal. Dichroism has the property of absorbing the ordinary light and produces the polarized light. Similarly Polaroid are the devices used to produce plane polarized light. It is made from the crystal of iodosulpahate of quinine in thin sleet mounted between two thin sheets of glass of cellulose. When the unpolarised light falls on the polariod, only the electric field vector oscillatingin a the direction perpendicular to the alignment of molecules passes through polariodso, the transmitted light has the electric field vector oscillating perpendicular to the in the direction of the alignment of the molecules.
These transmitted light are plane polarized. When the unpolarised beam of light falls on the molecules of dust particles or molecules, beam get scattered to be polarized. It is because every molecules acts like a electric dipole that absorbs energy from the incident particle and set the electric dipole of the molecule into the vibration and radiates the light of the same frequency as that of incident, in the form of polarized light.
When the ordinary light is incident on the transparent media like water and glass at polarizing angle the ray of light after the reflection become s plane polarized lightbecause that every vibration of the electric vector can be resolved into parallel and perpendicular components to the plane. The angle of incidence and reflection are i p i. The angle of refraction is r. Brewster law states that the tangent of the polarizing angle is equal to the refractive index of the medium.
Polaroid are the devices used to produce plane polarized light. When the unpolarised light falls on the polariod, only the electric field vector oscillating in the direction perpendicular to the alignment of molecules passes through polariod so, the transmitted light has the electric field vector oscillating perpendicular to the in the direction of the alignment of the molecules.
