A scattering-invariant mode of light is generated by a spatial light modulator. This modulated beam propagates through free space (top) or a strongly scattering medium (bottom) such that the pattern ...

Light's behavior seems counterintuitive. That is, until you figure out light is a wave. The way light behaves can seem very counterintuitive, and many physicists would agree with that, but once you ...

An experiment 180 years ago first demonstrated a connection between light and electromagnetism – but the link is deeper than ...

Researchers in Europe have developed a technique for obtaining accurate laser-based measurements of objects hidden behind complex scattering structures. They say that their mathematical formula, which ...

Tiny structures that use light waves to perform ultrafast complex mathematical operations could be built from available materials, a new computer simulation suggests. The study could soon lead to new ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. One of the greatest scientific achievements in all of human history was ...

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...

This artist's concept depicts a twisted vortex beam striking the gated photodetector, which filters the waveform by matching its twist pattern. This allows scientists to embed data in the waveform.

Light is more than what we see. The Sun sends out a number of waves of light in different wavelengths. Find out about wavelengths and the electromagnetic spectrum. Science Trek is available to stream ...

Researchers show how to control Dirac plasmon polaritons, paving the way for powerful terahertz photonic devices with faster, more efficient performance. (Nanowerk News) Scientists are finding new ...

In “What is Light?”, we described light as both a wave and a particle under the conditions of the wave-particle duality. In the previous posts, we have mostly modeled light as a ray when discussing ...
