Incident electromagnetic radiation
WebAn electromagnetic wave incident on the object exerts forces on the charged particles, ... The energy that sunlight carries is a familiar part of every warm sunny day. A much less familiar feature of electromagnetic radiation is the extremely weak pressure that electromagnetic radiation produces by exerting a force in the direction of the wave ... WebWhen electromagnetic radiation strikes perpendicular to a flat surface, a totally absorbing surface feels radiation pressure I0/c, where I0 is the intensity of incident electromagnetic radiation. A totally reflecting surface feels twice that pressure.
