A light wave could be an electromagnetic wave that travels through the vacuum of outer space. Light waves are made by moving electric charges. An electromagnetic wave is a transversal wave that has an electrical and a magnetic component.

Unpolarised light can be transformed into polarised light. Light waves that are polarised have oscillations of electric fields that occur in a single plane. Polarisation is the process of converting unpolarised light into polarised light. Polarising light can be done in a variety of ways.

Ans. We can use a Nicol prism placed against the light source to find if the light is plane-polarised or not. If the source light is plane-polarised while rotating the Nicol prism against the light, we can find two distinct places where the intensity of the light completely extinguishes.

Light waves are transverse: that is, the vibrating electric vector associated with each wave is perpendicular to the direction of propagation. A single vertical oscillation of light waves can pass through a vertical slit. Still, when a horizontal light wave oscillating passes through a vertical slit, it cancels and gets blocked by the slit. Thus, a plane-polarised light is a light wave that oscillates along a single plane. This process of converting unpolarised light into a plane-polarised one is known as polarisation. Polarisation is used in polaroid cameras, sunglasses, lenses, laboratories, polaroid sheets, etc.

Ans. A light that has altered the directions of its wave in such a way that it only moves through one plane is called polarised light.

Ans. Light is an electromagnetic wave that is transverse in nature. Unpolarised light has waves moving in all directions.

Ans. An ordinary light that we see in our everyday life is an unpolarised light. It has transverse waves moving in all directions, while a plane-polarised light comes only in one plane, meaning it has a wave that moves only in one direction.

Ans. A light that has altered the directions of its wave in such a way that it only moves through one plane is called polarised light.

A light wave that oscillates electric fields in addition to one plane is observed as unpolarized light. lightweight emitted by the sun, by a lamp within the classroom, or by light is unpolarized light. Such light waves are created by a number of electric charges that vibrate, therefore making an electromagnetic wave that oscillates the electric field in a variety of directions. This idea of unpolarized lightweight is quite troublesome to visualise.

A device for converting unpolarised light into a plane-polarised one is a polariser. A polariser is usually a polaroid sheet. A polaroid film or a polaroid sheet consists of molecules arranged in parallel columns to each other. The space between any two adjacent columns in the molecules of the sheet acts to allow light with only a specific orientation to pass through. They are spaced and arranged in such a way to allow only one desired plane of light to pass through. All other lights with an electric field that do not have the same orientation are absorbed. In this way, all the unpolarised light transforms into plane-polarised or polarised light.

The article discusses in detail the application of polarisation of the electromagnetic waves of light. A brief discussion on Polaroids. The article also includes the definition, principal, methods.

Ans. An ordinary light that we see in our everyday life is an unpolarised light. It has transverse waves moving in all directions, while a plane-polarised light comes only in one plane, meaning it has a wave that moves only in one direction.

Vehicles, smartwatches, calculators, laptops, mobiles, television screens, railways station indicators, vehicles, aircraft, and such implement polaroids. One can even see the use of polarisers more clearly in the lens of cameras. The lens of a camera is a polaroid. While placing two lenses in front of each other and rotating them against a light source, we can see an alternate dimming of the light. This is due to the direction in which they are polarised. With such vital applications, a polariser is used almost in everything in our day-to-day lives.
