| Abstract: | Formulae for the radiation pressure of electromagnetic and of sound waves are reviewed. The pressure on an obstacle in the path of the waves can be calculated from the momenta of the incident and scattered trains, and it is now well established that any train of waves of intensity J propagated with speed v has momentum J/v 2 per unit volume. A general proof of this result is proposed, independent of the nature of the waves. |
