This is a groundbreaking, first-ever image of light behaving simultaneously as both a wave and a stream of particles. This historic image was made by scientists at the Ecole Polytechnique Federale de Lausanne, Switzerland, led by Fabrizio Carbone. The team used electrons to image a standing wave of light. Phys.org explains: "As the electrons pass close to the standing wave of light, they 'hit' the light's photons particles, changing photon 'energy packet' speeds that also showed up in the image as particles."
