2. Forces induced by light scattering: volumetric stresses

While radiation pressure at an interface produces a transient flow until equilibrium is reached with Laplace pressure and buoyancy, the propagation of light in a scattering medium can induce a volume force within a liquid through momentum transfer to the scatterers  , which creates a steady flow (flows induced by optical absorption will be discussed in §
