Absorption Spectrum

Science / Chemistry / Absorption Spectrum: A plot that shows how much radiation a substance absorbs at different wavelengths. Absorption spectra are unique for each element and compound and they are often used as chemical 'fingerprints' in analytical chemistry. The spectrum can represented by a plot of either absorbance or transmittance versus wavelength, frequency, or wavenumber.

Specific Absorption Rate (SAR)

Technology / Cell Phones / Specific Absorption Rate (SAR): A measure of the rate at which RF energy is absorbed by the body. MORE

Reabsorption

Science / Biology / Reabsorption: The return to the blood of most of the water, sodium, amino acids, and sugar that were removed during filtration; occurs mainly in the proximal tubule of the nephron. MORE
