Absorption Coefficient (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 absorption coefficient of a material is a critical factor in determining its optical properties and is often used in applications such as solar cells and optical filters.
- Researchers measured the absorption coefficient of the new nanomaterial to assess its potential for use in biomedical imaging applications.
- The absorption coefficient of the water sample was used to estimate the concentration of the contaminant in the solution.
- The team used a spectrophotometer to determine the absorption coefficient of the sample as a function of wavelength.
- A high absorption coefficient indicates that a material is efficient at absorbing radiation, which is essential for applications such as laser-induced breakdown spectroscopy.
