# Attenuation coefficient, spectral μ(λ)

Sum of the scatter coefficient s and the absorption coefficient a:

$\mu \left( \lambda \right) = s \left( \lambda \right) + a \left( \lambda \right)$

The coefficient indicates the degree to which a light beam is weakened by a medium as a result of undissolved and dissolved substances.
