An object scatters an incident plane wave with E_inc(r, t) = ê₀E₀ exp[i(k₀ · r − ωt)]. Use the Maxwell stress tensor formalism to show that the time-averaged force on the object can be written in terms of the incident wave intensity Iinc, the total cross

 section σtot, and the differential cross section for scattering dσ_scatt/dΩ as

The projection of this force on the direction k̂₀ is often called the radiation pressure due to scattering.
