REEMISSION Meaning and
Definition
-
Reemission refers to the process of releasing electromagnetic radiation or particles that were previously absorbed by a material or substance. It involves the emission of energy or particles by a substance that has previously absorbed energy through radiation or particle interaction.
In the context of electromagnetic radiation, reemission occurs when photons that have been absorbed by a material are subsequently re-emitted as new photons. This process can be understood in terms of the energy levels of the absorbing material. When radiation of a specific energy, such as light, is absorbed by the material, the energy is transferred to the electrons within the material, causing them to move to a higher energy level. Reemission takes place when these excited electrons transition back to their original lower energy level, releasing the absorbed energy in the form of a new photon.
Reemission can also occur with other particles, such as in the interaction between atomic nuclei and neutrons. In this case, reemission involves the release of neutrons by a nucleus that had previously absorbed neutrons during a nuclear reaction.
Overall, reemission is a fundamental process in physics that occurs when energy or particles are emitted by a material or substance that has previously absorbed them. It plays a significant role in various fields, including spectroscopy, radiation physics, and nuclear reactions.

Etymology of REEMISSION
The word "reemission" is derived from two roots: "re-" and "emission".
The prefix "re-" comes from the Latin word "re", which means "again" or "back". This prefix is used to indicate repetition or returning to a previous state.
The root "emission" comes from the Latin word "emissio", meaning "sending forth" or "release". It is derived from the verb "emittere", which consists of "e" (meaning "out") and "mittere" (meaning "send"). In English, "emission" refers to the act of sending out or discharging something, often in the context of energy or particles.
Putting these two elements together, "reemission" refers to the act of sending out or emitting something again or repeatedly.
