This law sets the quantity it explains equal to two minus the log of transmissivity, and that quantity can also be calculated as the product of path length, concentration and the extinction coefficient.
One modification of this law allows for its applicability to the analysis of tissue in near-infrared spectroscopy and was developed by Maikala. This law can be derived by treating molecules as opaque disks whose cross sectional areas are encountered by a certain particle and integrating the product of this area and the number of particles in an infinitesimally thin slab. This law sets the quantity it explains equal to two minus the log of transmissivity, and that quantity can also be calculated as the product of path length, concentration and the extinction coefficient. For 10 points, name this law that relates the properties of a material to the absorbance of light traveling through it.
