razele

Razele is the definite plural form of the Romanian noun rază, meaning a beam or ray of light, a line of sight, or a mathematical ray. The term is used across optics, physics, astronomy, and geometry, as well as in everyday language to describe directional light or radiation. The indefinite plural is raze, while razele denotes the specific set of rays that is being referred to in context.

In physics and optics, razele refer to streams or bundles of light or radiation, such as razele luminii solare entering a room, or specialized terms like razele X and razele gamma describing X-rays and gamma rays. In geometry, a rază is a half-line that starts at a fixed point and extends infinitely in a given direction; razele can describe multiple such rays emanating from various origins.

The word derives from Latin radius, via early Romanian development. The definite plural razele is formed with the standard Romanian pattern for feminine nouns, signaling that the rays in question are known or identified within a discourse.

Razele are a common term in scientific and educational contexts when discussing light, radiation, or geometric constructions, and they appear in both formal texts and technical explanations.
