Morphology

ultraviolet + illumination

The phrase is compositionally built from 'ultraviolet' (radiation beyond violet) modifying 'illumination' (light), so a learner who knows both words can infer it refers to light in the ultraviolet range. This follows a regular adjective + noun pattern and is cross-linguistically transparent, making it readily understandable to a B1 learner.

Etymology

Ultraviolet illumination comes from the idea of light just past the violet color we can see. Ultra means 'beyond', violet is the color, and illumination means 'lighting', so the phrase describes using that special, invisible light to reveal things.
