The film explores the properties of light, including reflection and refraction, through various experiments. It demonstrates how light travels in straight lines, how mirrors can reflect images, and ...

(Nanowerk News) Light travels at a speed of about 300,000,000 meters per second as light particles, photons, or equivalently as electromagnetic field waves. Experiments led by Hrvoje Petek, an H.K.

Imagine building a Lego tower with perfectly aligned blocks. Each block represents an atom in a tiny crystal, known as a quantum dot. Just like bumping the tower can shift the blocks and change its ...

A ghost is haunting our universe. This has been known in astronomy and cosmology for decades. Observations suggest that about 85% of all the matter in the universe is mysterious and invisible. These ...

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 ...

An international research group has developed a new X-ray spectroscopy method based on the classical double-slit experiment to gain new insights into the physical properties of solids. An ...

Topological insulators are one of the most puzzling quantum materials - a class of materials whose electrons cooperate in surprising ways to produce unexpected properties. The edges of a TI are ...

A new study found that Weyl semimetals, a class of quantum materials, have bulk quantum states whose electrical properties can be controlled using light. Insights from quantum physics have allowed ...
