Preferred Label : depth of penetration;
Detailed label : depth of penetration of light;
IUPAC definition : The inverse of the absorption coefficient. If the decadic absorption coefficient,
a, is used, the depth of penetration (1/a) is the distance at which the radiant power,
P λ, decreases to one tenth of its incident value, P λ 0. If the Naperian absorption
coefficient, α, is used, the depth of penetration (1/α β in this case) is the distance
at which the radiant power decreases to 1/e of its incident value.;
