Researchers have shown through the use of optical traps that they can throw and catch individual atoms using light on the smallest field imaginable.
In a darkened room, we will hold a red LED flashlight to our thumb. The thumb will glow bright red indicating much of the light passed right through our thumb. When we hold a green LED flashlight to our thumbs however, almost all of the light is absorbed.
Scientists have long believed that light can behave as both a particle and a wave but until today – it’s been a bit difficult to visualize and impossible to photograph. Now, researchers in Switzerland have taken the first ever picture of light as both a wave and a particle – and it’s a beauty!
