Definition of the noun absorptance
What does absorptance mean as a name of something?
noun - plural: absorptances
- a measure of the rate of decrease in the intensity of electromagnetic radiation (as light) as it passes through a given substance; the fraction of incident radiant energy absorbed per unit mass or thickness of an absorber
- example: absorptance equals 1 minus transmittance
- lexical domain: Quantities - nouns denoting quantities and units of measure
- synonyms of absorptance: absorption coefficient / coefficient of absorption
- more generic word: coefficient = a constant number that serves as a measure of some property or characteristic
Alternative definition of the noun absorptance
- [physics] the ability of an object to absorb radiation, measured as the ratio of absorbed flux to incident flux.
