What is called polarization of light waves, definition, uses (Polarisation of light waves in Hindi)

Definition of Polarization of Light Waves

Polarization of light wavesThe diffraction and interference of light confirms that light moves in the form of waves or that the nature of light is wave-nature.

But from these experiments it is not known what kind of waves these waves are-transverse waves or longitudinal waves , The polarization of light confirms that the light wave Transverse There is wave.

According to modern scientists, light waves one of a kind electromagnetic field waves in which electric and magnetic fields are mutually perpendicular to each other and vibrate in planes perpendicular to the direction of propagation of the wave, that is, if the wave is traveling in the direction perpendicular to the plane of the paper, then electric and magnetic The vibrations will be at the bottom of the paper.

It is known from experiments that electric vibrations are mainly responsible for the transmission of light. Since light waves are transverse waves

These electric vibrations are perpendicular to the direction of propagation of the wave when these vibrations occur randomly in each direction located in the plane. वितरित (Randomly distributed) If so, then this type of wave Unpolarized wave it is said.

The light waves emitted from the light sources used in daily life like electric bulb, tubelight etc. are non-polar waves.

But if they are not distributed equally in all directions in the electric vibration plane but are in the same direction, then such light waves are called Polarized waves it is said.

Nowadays to produce plane polarized light Polaroids make use of. It is a large film that is placed between two glass plates. this movie Nitro cellulose And Herpathite Made of a mixture of

Polaroids are of great use in our lives. For example, they are used to avoid the glare of light reflected from water-soaked roads, excessive white light, or bright floors, etc.

When two cars approach each other, glare due to their light can lead to an accident. To prevent this, Polaroids are used in cars.

Three-dimensional pictures in the cinema wearing Polaroid glasses (three dimensional pictures) is seen. Similarly in photography, in finding the concentration of sugar in a solution, in studying the optical properties of metals. Polaroids Is used.
