Morphology

radiant + flux

Both constituents contribute directly: 'radiant' (emitting light or energy) modifies 'flux' (a rate or flow), so the phrase literally denotes the rate/flow of radiant energy. The structure is fully compositional and follows common noun-modifier patterns, so a learner who already knows both words can infer the technical meaning, despite its specialised usage.

Etymology

Radiant flux paints a simple picture: radiant means shining or sending out energy and flux means a 'flow'. So radiant flux is the 'flow' of 'light energy' — how much light-energy passes each second, which is why we use it to measure a light source's power.
