Light can behave in very unexpected ways when you squeeze it into small spaces. In a paper in the journal Science, Mark Brongersma, a professor of materials science and engineering at Stanford ...

Flexible, layered materials textured with nanoscale wrinkles could provide a new way of controlling the wavelengths and distribution of waves, whether of sound or light. The new method, developed by ...

According to Physics Web in Sound breaks the light barrier (Free reg. required), a professor of physics in Tennessee has designed an experiment which proves that sound can move faster than light. This ...

Zap an optical fibre with a couple of laser beams and the resulting interference pattern causes an interesting effect–it squeezes the material, an effect known as electrostriction. This creates a ...

We are surrounded by waves. tiny vibrational waves transport sound to our ears. Light waves stimulate the retinas of our eyes. Electromagnetic waves bring radio, television and endless streaming ...

Taking pictures of the inside of the human body is something that we take for granted. But really, most current imaging systems are less than ideal. When it comes to getting the details without ...

Nothing can travel faster than light… except for sound. This is the claim of some US physicists, who say they have designed an unusual waveguide to make sound move at “superluminal” speeds (Appl. Phys ...

TL;DR: This experiment may not revolutionize telecommunications, but it highlights how accessible these concepts have become outside traditional research labs. Using nothing more than an iPad, a solar ...
