Extinction coefficient
Appearance
Extinction coefficient refers to several different measures of the absorption of light in a medium:
- Attenuation coefficient, sometimes called "extinction coefficient" in meteorology or climatology
- Mass extinction coefficient, how strongly a substance absorbs light at a given wavelength, per mass density
- Molar extinction coefficient, how strongly a substance absorbs light at a given wavelength, per molar concentration
- Optical extinction coefficient, the imaginary part of the complex index of refraction
