The first photograph of light as a wave and a particle

Einstein showed us in 1909 that light can behave both as a particle and a wave, but we are yet to see a photograph of light in both states simultaneously, until now! Scientists at the École polytechnique Fédérale de Lausanne, Switzerland, have managed to capture the image of light exhibiting both properties. The breakthrough work has been published in Nature Communications and explains how researchers used laser pulses on a nanowire, showing wavelength moving in two directions and where they meet, show a standing wave (a particle). Regarding the moving waves, an electron beam on the nanowire caused a change in speed at which the electrons moved. The image was captured as the waves met. Photo: Fabrizio Carbone/EPFL Full article:
