LIGHT RAY Meaning and
Definition
-
A light ray is a fundamental concept in physics, specifically in optics, used to describe the path that light travels in a straight line. It is a narrow beam of light that can be represented as a straight line with an arrow indicating its direction of propagation. Light rays are used to analyze and understand the behavior of light when it interacts with various materials or passes through different mediums.
Light rays travel at a constant speed in a vacuum, typically referred to as the speed of light, denoted by "c." However, when light encounters a medium other than a vacuum, such as air, water, or glass, its speed can change, causing the light ray to deviate from its original path. This phenomenon, known as refraction, is the bending of light as it passes through different materials.
Additionally, light rays can be reflected off surfaces, producing the phenomenon of reflection. Depending on the angle at which the light ray strikes the surface, it can be totally reflected back or refracted into a different direction. This behavior is governed by the laws of reflection and refraction, which can be mathematically described using principles such as Snell's law.
Overall, the concept of a light ray provides a simplified abstraction to analyze and understand the behavior of light in various optical systems and materials, facilitating the exploration of phenomena such as reflection, refraction, and diffraction.

Etymology of LIGHT RAY
The term "light ray" is derived from two different words: "light" and "ray".
The word "light" originated from the Old English word "liht" which means "bright, shining, or clear". It is related to the Middle Low German word "lēcht" and the Dutch word "licht".
The word "ray" comes from the Middle English word "raye" or "rai" which means "beam of light". It can be traced back to the Old French word "rai" or "raie", meaning "ray" or "stripe". These French words have their origins in the Latin word "radius" which means "spoke" or "ray" (of light).
Therefore, the term "light ray" combines the Old English and Germanic origins of "light" with the French and Latin origins of "ray" to refer to a narrow beam or stream of light.
