First ever photograph of light as a particle and a wave
In a breakthrough, Swiss scientists have succeeded in taking the first ever photograph of light behaving both as a wave and as a particle. Even though a variety of experiments have successfully observed both the particle- and wave-like behaviours of light, they have never been able to observe both at the same time.
Geneva: In a breakthrough, Swiss scientists have succeeded in taking the first ever photograph of light behaving both as a wave and as a particle. Even though a variety of experiments have successfully observed both the particle- and wave-like behaviours of light, they have never been able to observe both at the same time.
The research team carried out an experiment using electrons to image light. Light travels along this tiny wire in two possible directions, like cars on a highway. When waves travelling in opposite directions meet each other they form a new wave that looks like it is standing in place. Here, this standing wave becomes the source of light for the experiment, radiating around the nanowire. This phenomenon shows the wave-like nature of light, it simultaneously demonstrated its particle aspect as well.
