Reflection and Refraction are key items in terms of understanding our world and how light brightens up everything. Why do straws appear to break in a glass of water? Why does a rainbow exist and how ...

Introduction Can you imagine a bouncy ball that could bounce back and forth between two walls, infinitely—that is, forever? Wouldn't that be amazing? What if, instead of a ball, light was bouncing ...

When we look in a mirror, we are used to seeing our faces looking back at us. The reflected images are produced by electromagnetic light waves bouncing off of the mirrored surface, creating the common ...

Metasurfaces are two-dimensional (2-D) metamaterials that can control scattering waves of a light beam. Their applications include thin-sheet polarizers, beam splitters, beam steerers and lenses.

Researchers demonstrate a new technique for suppressing back reflections of light, leading to better signal quality for sensing and information technology. Researchers demonstrate a new technique for ...

Science, it is sometimes claimed, is neutral: it is up to society to decide how to employ research findings. Yet society often struggles with its end of the deal. That is because science can also hold ...

For more than 50 years, scientists have theorized that a special kind of reflection known as time reflections have existed in the realm of quantum mechanics. However, proving the existence of this ...

Physicists have finally confirmed a phenomenon that sounds like pure science fiction: waves that appear to bounce off a sudden change in time rather than a surface in space. The effect, known as a ...
