RAYLEIGH Meaning and
Definition
-
Rayleigh is a term derived from the name of the famous British physicist Lord Rayleigh, also known as John William Strutt. In physics and engineering, Rayleigh refers to two related concepts: the Rayleigh scattering and the Rayleigh criterion.
Rayleigh scattering is the scattering of electromagnetic radiation, such as light or radio waves, by particles or molecules significantly smaller than the wavelength of the radiation. It occurs when the radiation interacts with the particles, causing it to change direction and be scattered in various directions. This phenomenon is responsible for the blue color of the sky during clear daylight, as the shorter blue wavelengths are scattered more than the longer red wavelengths.
The Rayleigh criterion, also known as the Rayleigh resolution criterion, is a criterion used in optics to determine the theoretical limit of spatial resolution or the minimum separation between two distinguishable points or objects in an optical system. According to this criterion, two points are considered just resolvable if the peak of one point spread function coincides with the first minimum of the other point spread function. It is primarily used in assessing the performance of optical devices, such as telescopes and microscopes.
Both the Rayleigh scattering and the Rayleigh criterion are fundamental concepts in their respective fields, providing insights into the behavior of light and other forms of electromagnetic radiation. Understanding these concepts is crucial for advancements in the fields of optics, atmospheric science, and telecommunications, among others.

Etymology of RAYLEIGH
The word Rayleigh primarily has two different etymological origins, depending on the context:
1. In physics: The term Rayleigh in physics is named after Lord Rayleigh (John William Strutt), a British physicist. He made significant contributions to the study of wave theory, especially in the fields of acoustics and optics.
2. In geography: Rayleigh is also the name of a town in Essex, England. The etymology of the town's name is believed to have Old English origins. It is derived from the phrase raege (meaning roe deer) and leah (meaning woodland or clearing). Therefore, Rayleigh may refer to a clearing in the woods where roe deer can be found.
