Capture 'light' form in both wave and particle form

For the first time in the world, Swiss scientists have taken a light photo that works under both waveform and particle form at the same time.

Scientists have long known that light is a wave of waves. That's why bendable light bends around buildings and wriggles through tiny needle holes. Different wavelengths of light are the reason why we can observe different colors and make the same dress that people look blue and black, others look yellow and white. , even someone looks blue and yellow.

However, all the characteristics and behavior of a wave band are not enough to explain everything that light creates. For example, when light hits the metal, it emits a stream of electrons. Einstein's physics genius once explained this phenomenon in 1905 that light is also made of particles and those particles strike metal electrons like billiard balls, causing them to fly. go. This view ultimately helped Einstein win the Nobel Prize, but scientists are still not satisfied with being forced to admit that light can behave both as a wave and as a particle.

It has been more than 100 years and until recently, all experiments with light that any scientist has ever done demonstrate light or act like a wave, or as a particle, but never before 2 at the same time.

Recently, however, researchers from the Swiss Federal Institute of Technology have documented the bizarre division of light using a new imaging technique.

First, they fired laser light at a tiny metal wire. This helps to trap the light waves on the wire.

Later, the team fired a stream of electrons along the metal wire. The light waves on the wire are made up of light particles called photons, so the electrons hit and bounce away from the photons, causing some electrons to accelerate, while others decelerate. Changes in velocity reveal like visible energy spots.

Experts have placed metal wires under a massive microscope, able to observe electrons and take a picture of them. The bottom of the image shows the location of light particles and the top layer reveals how light looks like a wave band.

"This experiment shows, for the first time, we can film the quantum mechanics and its paradoxical nature directly," stressed researcher Fabrizio Carbone.

According to Mr. Carbone, the above imaging technique could help promote the development of quantum computers - super-fast computers take advantage of other strange properties of light particles.
