RERADIATION Meaning and
Definition
-
Reradiation refers to the process by which electromagnetic radiation is emitted or scattered by a medium after being absorbed and re-emitted. When radiation, such as light or heat, passes through a medium, some of its energy may be absorbed by the atoms or molecules in that medium. These atoms or molecules, upon absorbing the energy, become excited and then release the absorbed energy as electromagnetic radiation of the same or different wavelength.
In the context of science and physics, reradiation commonly occurs when the absorbed radiation is re-emitted in a different direction or wavelength from the incident radiation. This phenomenon is essential in various fields like astronomy, atmospheric science, and telecommunications.
In astronomy, reradiation from different celestial bodies is often observed to gather information about their composition and physical characteristics. For instance, reradiation of energy in the form of radio waves from distant galaxies or stars can be received and analyzed by radio telescopes, providing astronomers with valuable data.
In the field of telecommunications, reradiation may occur during the propagation of signals through various media, such as cables, fiber optics, or wireless channels. Signal reradiation allows for information transfer and communication between devices, enabling the transmission of data, voice, or video communications over long distances.
Overall, reradiation plays a critical role in the understanding and application of electromagnetic radiation in various scientific and practical domains.
Common Misspellings for RERADIATION
Etymology of RERADIATION
The word "reradiation" is derived from the combination of two root words: "re" and "radiation".
The prefix "re-" comes from Latin and means "again" or "back". It is commonly used to indicate repetition, restoration, or return.
The word "radiation" comes from the Latin term "radiare", which means "to emit rays or beams". In general, radiation refers to the emission of energy in the form of waves or particles.
When "re-" is added to "radiation", it forms "reradiation", which means the re-emission or the repetition of emission of radiation. It specifically refers to the retransmission or re-emission of radiant energy, either in the same form or in a modified form, after it has been absorbed or reflected.
