Momentum Transport in Electromagnetic Plane Wave The momentum transported by an electromagnetic wave is proportional to the energy transported. Momentum density: ~ p V = ~ S c 2 , where ~ S = 1 μ 0 ~ E × ~ B is the Poynting vector. When the wave is absorbed by a material surface it exerts an impulse ~ F dt = Δ
