How Do You Spell POLARISATION OF LIGHT?

Pronunciation: [pˌə͡ʊləɹa͡ɪzˈe͡ɪʃən ɒv lˈa͡ɪt] (IPA)

Polarisation of light is spelled with two "l" letters, with the first "l" being silent. The IPA phonetic transcription for this word is /pəʊləraɪˈzeɪʃ(ə)n əv laɪt/. The "p" sound is made with the lips, followed by a short "o" sound and a silent "l". The stress is on the second syllable, which is pronounced with a long "i" sound. The word is then followed by a "z" sound, an "eɪ" diphthong, and a "ʃ" sound. The final syllable is pronounced with a short "a" sound and a long "i" sound, followed by a "ʃ" sound.

POLARISATION OF LIGHT Meaning and Definition

1. Polarisation of light refers to the phenomenon in which the waves of light oscillate in a specific direction, known as the plane of polarisation. While light is typically made up of electromagnetic waves that vibrate and propagate in all directions perpendicular to their path of travel, polarised light restricts these vibrations to a single plane. This means that the electric field vector of polarised light remains confined within a particular direction.

   Polarisation occurs when unpolarised light passes through certain filters or materials that selectively transmit certain orientations of light waves over others. These filters or materials only allow waves vibrating parallel to a particular axis to pass through, which effectively filters out waves vibrating in other perpendicular directions. This process, known as polarization filtering, polarizes the light by favoring one specific plane of oscillation.

   The phenomenon of polarisation of light has several important practical and scientific applications. It is widely used in various optical devices such as sunglasses, 3D glasses, and LCD screens to reduce glare, improve visibility, and control the transmission of light. Polarised light is also used in scientific research and experimentation, particularly in materials science, microscopy, and the study of crystals.

   Overall, polarisation of light describes the alignment and restriction of light waves to a specific plane of oscillation, achieved through polarization filtering. This phenomenon has significant implications in various fields and finds numerous applications in both everyday life and scientific endeavors.

2. The change produced on rays of light by the action of certain media through which they pass, or by the action of certain surfaces which reflect them, so that they cease to exihbit the usual phenomena of trausmission in the one case, and reflection in the other, besides possessing other new properties.
