    Extinction coeffiecient
    Hello,
    What is the importance of extinction coefficient? And molar extinction coefficient? If the value is too large like 100000,what information we get from it?

    The extinction coefficient describes how well a substance scatters and absorbs EM radiation. It's a function of the material and the wavelength of the EM.

    Something like glass would have a very low extinction coefficient for visible light as it is hardly absorbed or scattered even through very thick panes of glass, whereas something like wood would have a very high coefficient, since almost all light is scattered and absorbed within a very small distance.
