Scientists have demonstrated that atoms can exhibit wave-like behavior, challenging long-held assumptions that experiments of this nature were impossible and opening new doors in quantum physics. The ...

First experimental observation of matter-wave diffraction in a short-lived electron-positron atom using a graphene-based diffraction grating. (Nanowerk News) One of the discoveries that fundamentally ...

THE apparatus for this experiment consists of a slit and a grating. A slit may be made by ruling a line on a piece of smoked glass. The grating is made by slightly greasing the thumb and forefinger ...
