Three physicists from RIKEN have illustrated the ability of an ultrafast form of transmission electron microscopy to quantify sound waves in nanostructures. A cutaway of the ultrafast transmission ...

Researchers at the Department of Energy's SLAC National Accelerator Laboratory. Stanford University, and Denmark Technical University have designed a cutting-edge X-ray microscope capable of directly ...

So far we have only considered sound in isolation and we have seen that sound has velocity, frequency, wavelength and reduces in intensity in proportion to the square of the distance from the source.

Metamaterials researchers have created a thin plastic structure with geometric details allowing it to control the redirection and reflection of sound waves with almost perfect efficiency.
