Optical Illusions: Afterimage science + ghosts
Have you ever seen a ghost? How about an after-image? Our bodies aren’t perfect and they sometimes make mistakes, resulting in fun optical illusions.

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…
