Diffraction spikes, visible in high-power astronomical images, are an intrinsic optical phenomenon in reflecting telescopes, primarily caused by the diffraction and subsequent interference of incoming ...

A variety of ultrathin nanomechanical diffraction gratings that have been fashioned from the “wonder material” graphene have been created by an international team of researchers. The team wanted to ...

At the quantum boundary This experiment at the University of Vienna proves that objects as big as molecules can interfere. (Image: Robin Riegler) Ever since quantum theory was developed during the ...
