What is the absorption coefficient?
Posted December 1, 2020

Answer

The absorption coefficient or attenuation coefficient, describes how readily a beam of light can pass through a volume of material. It can be calculated using the following formula:

  • α= absorption coefficient
  • f= frequency of the monochromatic light
  • k= extinction coefficient
  • c= the speed of light
  • π= constant pi (~3.14)
