Concept information
Preferred term
radiation pressure
Definition(s)
- Radiation pressure is the mechanical pressure exerted upon any surface due to the exchange of momentum between the object and the electromagnetic field. This includes the momentum of light or electromagnetic radiation of any wavelength that is absorbed, reflected, or otherwise emitted (e.g. black-body radiation) by matter on any scale (from macroscopic objects to dust particles to gas molecules). The associated force is called the radiation pressure force, or sometimes just the force of light. (Wikipedia, The Free Encyclopedia, https://en.wikipedia.org/wiki/Radiation_pressure)
