Is light a particle or a wave

While it has been known that light behaves as both a particle and a wave for some time, no one had been able to observe light in both these states at the same time. Until a research team at EPFL, led by Fabrizio Carbone carried out an experiment using electrons to image light.

Now we have the first time ever snapshot of light behaving simultaneously as both a wave and a stream of particles.
