strålens

Strålens is the genitive form used in Swedish and Norwegian for the definite noun stråle, meaning ray or beam. The possessive is formed by adding the suffix -s to the definite form strålen, producing strålens, which translates to “the ray’s” or “of the ray.” This grammatical construction is common in technical and descriptive writing when attributing properties to a specific ray rather than to rays in general.

In practice, strålens appears in phrases such as strålens riktning (the direction of the ray), strålens intensitet (the ray’s intensity), and strålens hastighet (the ray’s speed). In optics and physics contexts, discussing strålens properties allows precise reference to a particular ray produced, for example, by a laser, a light source, or a particle beam.

Notes on usage: strålens is tied to the definite form of the noun and is not a separate lexical item with meaning beyond possession. It is commonly found in scientific descriptions, lab notes, and educational texts in Swedish and Norwegian. Some related terms include stråle (ray/beam), strålning (radiation), and ljusstråle (light ray).
