... This theory was tested in 1922 by A.H. Compton. He directed X-rays (which have short wavelength, therefore high energy) at a graphite target. The rays were scattered by the atoms in the graphite. Compton measured that the scattered X-rays had a longer wavelength, which means they had lost some energ ...

Its application, however, is limited to small objects, typically 100µm or smaller, because the technique can only apply forces in the pN range. It is estimated that only about 10−10 % of the light e ...
