  • Specialized
translation icon : densidad de transmisión
  • The transmission density of the filter determines how much light can pass through.

Examples

  • Scientists measured the transmission density to assess the material's suitability for optical lenses.

  • A higher transmission density usually means the sample is more transparent to electromagnetic radiation.

  • The transmission density of the glass was impressive.

  • Higher transmission density means better light penetration.

  • A higher transmission density usually means the sample is more transparent to electromagnetic radiation.

  • Scientists measured the transmission density to assess the material's suitability for optical lenses.

  • The transmission density of the filter determines how much light can pass through.

Morphology

transmission + density

The headword 'transmission' already denotes the amount of light or radiation that passes through, and 'density' denotes an amount per unit; together they transparently indicate a measured amount of transmission. Although somewhat technical, the noun+noun composition follows a common cross-linguistic pattern for measures, so a B1 learner who knows both constituents can infer the general meaning.

Etymology

Transmission density is a noun that names a measure of how much a material lets light pass through. Imagine shining a light through a window: if most light gets through, the material has high transmission and so high density in this sense, so transmission density tells you 'how much light passes through'.
