What does absorbance mean?
The extent to which a substance absorbs light, typically measured as a logarithmic ratio of the intensity of the incident light to the intensity of the transmitted light. In spectroscopy, it is a measure of the amount of light absorbed by a sample at a given wavelength.
Example
"The absorbance of the solution was measured using a spectrophotometer to determine the concentration of the dye."
