Due to the inhomogeneity of biological tissue and the impact between photons and microscope particles, photons are inevitably scattered and diverged from the incident direction when traveling in the ...

Physicists have finally turned a long standing thought experiment into a laboratory reality, showing that electromagnetic ...

Photons, for centuries both a puzzle and a tool, continue to help scientists illuminate nature at the smallest and largest scales. Photons, the fundamental particles of the electromagnetic field that ...

A new discovery shows that messy, stray light can be used to clean up quantum systems instead of disrupting them. University of Iowa researchers found that unwanted photons produced by lasers can be ...

Ultraviolet (UV) light has higher energy photons than visible light and, thus, has more applications. Researchers have now developed a brilliant innovation -- a solid-state material that can stably ...

Researchers are learning to flip light on and off one particle at a time, turning single photons into a controllable resource instead of a random byproduct of exotic materials. By engineering ...

Collide light with light, and poof, you get matter and antimatter. It sounds like a simple idea, but it turns out to be surprisingly hard to prove. A team of physicists is now claiming the first ...

The fundamental particle of light is both ordinary and full of surprises. What physicists refer to as photons, other people might just call light. As quanta of light, photons are the smallest possible ...

The speed of light is a fundamental constant, approximately 299,792,458 meters per second. It's the same for all observers and hasn't changed measurably over billions of years. Nothing can travel ...
