Coefficient Of Absorption (Noun)
Meaning
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; "absorptance equals 1 minus transmittance".
Classification
Nouns denoting quantities and units of measure.
Examples
- The coefficient of absorption was determined in the lab to calculate the rate at which different materials absorb light.
- Variations in the coefficient of absorption of certain substances are necessary for the proper functioning of solar panels.
- Understanding the coefficient of absorption of different materials is crucial in designing efficient window coatings for energy-saving buildings.
- Scientists measured the change in the coefficient of absorption of the sample after exposing it to high heat conditions.
- Researchers found the coefficient of absorption for a certain rare earth compound to be unusually high, making it useful in laser technology.
