(Phys.org)—Researchers have fabricated a silicon optical antenna that is somewhat like an extremely small, special kind of prism. This is because when a red light shines on the optical antenna, the light turns right, but ...
A hand-held laser pointer produces no noticeable recoil forces when it is "fired"—even though it emits a directed stream of light particles. The reason for this is its very large mass compared to the very small recoil impulses ...
