The double-slit experiment is one of the most famous experiments in physics and definitely one of the weirdest. It demonstrates that matter and energy (such as light) can exhibit both wave and ...

Gear-obsessed editors choose every product we review. We may earn commission if you buy from a link. Why Trust Us? Ever hear of the double slit experiment? It’s one of the most bizarre experiments in ...

The film explores the nature of sound waves, demonstrating how sound travels as a wave through air, which acts as a medium. It illustrates sound generation using a loudspeaker, examines oscillation, ...

Researchers have discovered how to control heat with a magnetic field. The study is the first ever to demonstrate that acoustic phonons -- the elemental particles that transmit both heat and sound -- ...

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 ...

The interference of sound waves is not just of academic interest. For instance, it is the operating principle of noise-cancelling headphones. These create their own sound vibrations, which are tuned ...

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.

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. This week, the US Food and Drug Administration gave the green light ...

THE principle that a regularly stratified medium selectively reflects a monochromatic beam of radiation incident on it at the appropriate angle is well known and forms the basis for the X-ray analysis ...

In a breakthrough that challenges conventional physics, scientists have confirmed the existence of “second sound” — a phenomenon where heat travels as a wave rather than dispersing slowly, as it does ...
