Light radiation pressure
WebRadiation pressure has recently been reexamined in the light of these new laser sources and has been found to be a strong effect. Indeed, the forces exerted by laser sources have … WebThe answer to that question depends on quite a number of factors: the range of wavelengths we can detect (dλ) the period of time over which we measure (dt) the area of the plate (dA) the solid angle of our detector (dΩ) the location of our detector, relative to the plate (θ) Putting all these pieces together,
