Webwith the optical intensity I.This equation contains the factor cos 2 θ rather than cos θ, because the angled incidence also increases the illuminated area on the mirror.. Modified equations can be derived for other situations; for example, if radiation is fully absorbed on a solid body, the radiative force is F = P / c.The factors of 2 and also cos θ are missing … Web27 mei 2024 · When light hits an object, this radiation exerts a certain force on that object and, with respect to the surface, also a certain pressure. This pressure is referred to as radiation pressure. In the particle model, it is relatively easy to understand how the pressure of radiation comes about. According to quantum mechanics, any propagating …
