Waves close wavesVibrations that transfer energy from place to place without the transference of matter. - including sound and light - can be reflected at the boundary between two different materials.

Researchers have developed new metasurfaces for the arbitrary manipulation of reflected waves, essentially breaking classical reflection law to engineer it at will. In our daily lives, we can find ...

Time reflections, or spatial reflections, occur when "electromagnetic radiation in the form of light or sound waves hit a mirror or wall, respectively," resulting in a reflection, like a mirror image ...

Sound waves can reflect off surfaces. We hear reflected sound waves as echoes. Hard, smooth surfaces are particularly good at reflecting sound. This is why empty rooms produce lots of echoes. Soft, ...

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or ...

New research by University at Buffalo and University of Colorado Boulder mathematicians has uncovered and characterized novel two-dimensional wave patterns — waves that propagate along two directions ...
