When two or more light waves interact with one another, they result in the formation of different interference patterns. British physicist Thomas Young first demonstrated and explained these patterns ...

If you ask people what a hologram is, they’ll probably describe the 3D light projections of science-fiction films — such as the vision of Princess Leia floating in free space in the 1977 film Star ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...

A new series of studies led by researchers from Tel Aviv University, the Technion and MIT has found that some properties of light waves emitted from particles depend on the wave properties of the ...

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 ...

A core tenet of quantum theory was imperilled this year when a team of researchers put forward a radical new interpretation of an experiment about the nature of light. At the centre of the new work ...
