- The solar wind and radiation pressure blow the smallest dust particles into a familiar comet dust tail.
- solar radiation pressure
- radiation pressure from the Sun
It does not have one of these gask discs around it that would lead to this radiation pressure that could cause an outflow.
- It does not have one of these gask discs around it that would lead to this radiation pressure that could cause an outflow.
- And so most of the paper is devoted to working out whether solar radiation pressure could explain this acceleration in a moment.
- OK, so there is a radiation pressure that is proportional to temperature.
Examples
-
The idea of solar sail spacecraft also relies on radiation pressure from the sun to propel them through space.
-
Within some emission nebulae, radiation pressure from young stars sculpts the surrounding gas into intricate shapes.
-
OK, so there is a radiation pressure that is proportional to temperature.
-
Eventually the radiation pressure became negligible.
-
Already by 1923, he and his student Alice Golsen had made the first accurate measurements of radiation pressure.

Eddington decided that it isn't just gas pressure that keeps a star from collapsing under gravity; radiation pressure is also important.
Academic text (1993) -
The group's experiment couples the radiation pressure force that is generated by light circulating inside a glass microsphere—about the size of a human hair—to the mechanical breathing motion of the microsphere.

Morphology
The meaning 'pressure exerted by radiation' is directly and transparently built from 'radiation' (energy emitted as rays/waves) combined with 'pressure' (force on a surface). This noun-noun composition follows a common, cross-linguistic compounding pattern (X + pressure = pressure caused by X), so a B1 learner who knows both constituents can readily infer the MWE's meaning.
Etymology
Radiation pressure comes from a simple image: radiation means light or similar energy and pressure means a push. Imagine sunlight like a very gentle wind that can 'push' tiny dust or small mirrors in space, so radiation pressure is the tiny push that light gives to a surface.
