Quantum mechanics tells us that light can behave simultaneously as a particle or a wave. We have never been able to directly observe both of these aspects of light at the same time: we either see it as a stream of particles or as a wave, but never both at the same time. However, scientists at EPFL have now succeeded in capturing the first-ever snapshot of this dual behavior of light.
Fabrizio Carbone and his research team at EPFL used electrons to visualize a “fingerprint of the wave-nature of light.” The experiment is explained in the following video:
