Extinction coefficient light
WebAs light passes through Earth's atmosphere, it suffers from two types of degradation: extinction: stars become dimmer seeing: stars become blurry Extinction Consider light … WebMar 5, 2024 · Mass extinction coefficient ε 1% refers to the absorbance of a 1% by mass solution. Typically this refers to an aqueous solution that we can take to have a density of 1000g/L. A 1% by mass aqueous solution would therefore refer to the dissolution of 10g/L, or a 10mg/ml solution of the molecule of interest.
