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 ...

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 ...

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 ...

Perhaps one of the most famous experiments in physics has been giving us the wrong message all these years. For nearly two centuries, the double-slit experiment has been providing a direct visual ...

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 ...

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 ...

For the past three years, humanity has known a new kind of astronomy from the traditional ones. No longer are we merely detecting light with a telescope, or neutrinos with enormous particle detectors, ...
