First Photo of Light as Wave and Particle
In 1905, Albert Einstein proposed that light has properties of both a wave and a stream of particles. Now, researchers in Switzerland have taken the first ever photo of light behaving both as a wave and as a stream of particles at the same time. The ability to observe light in this way could bring us a step closer to building super fast quantum computers, the researchers say. When UV light hits a metal surface it causes an emission of electrons. This is known as the photoelectric effect. A research…
