radiation pressure, corpuscular-radiation pressure(noun)
the minute pressure exerted on a surface normal to the direction of propagation of a wave
The pressure exerted by electromagnetic radiation on an object on which it impinges, as a consequence of its momentum.
Radiation pressure is the pressure exerted upon any surface exposed to electromagnetic radiation. The term can also refer to pressures generated by other forms of wave motion, e.g. acoustic radiation pressure. If absorbed, the pressure is the power flux density divided by the speed of light. If the radiation is totally reflected, the radiation pressure is doubled. For example, the radiation of the Sun at the Earth has a power flux density of 1,368.8485 W/m², so the radiation pressure is 4.6 µPa.
