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 • Optical extinction coefficient, the imaginary part of the complex index of refraction
WebWith 10-32 UNF threads and a body less than 3/4 ” long, these valves are often used to control flow in miniature pipelines. They have a 303 stainless steel body for good corrosion resistance. All are standard port, so they slightly restrict flow.. Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve … WebThe extinction coefficient bext is dependent on the presence of gases and molecules that scatter and absorb light in the atmosphere. The extinction coefficient may be considered as the sum of the air and pollutant scattering and absorption interactions, as shown in the following equation: (14.4)
