Light can behave in very unexpected ways when you squeeze it into small spaces. In a paper in the journal Science, Mark ...

Researchers have created a microphone that listens with light instead of sound. Unlike traditional microphones, this visual ...

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 ...

In the future, this method could also be used in technical applications with electromagnetic waves. Water, light and sound waves usually propagate in the same way forward as in a backward direction.

“It’s a technology that listens to the sound of light,” Yao says. “So, we shine light into the tissue, and we listen to the ultrasound generated in the process. By listening to the ultrasound of the ...

To get an idea of why making things spin with sound waves is difficult, picture a tube that holds a turbine. Normally, to make the turbine spin, a fluid would flow past the blades of the turbine.

Using liquid-filled optical fibers and sound waves, researchers at the Max Planck Institute for the Science of Light (MPL) in Erlangen have now discovered a new method to measure it.

Scientists have been unable to confirm the existence of time reflection due to the amount of energy required to create a ...

By adding a sound-mediated way to control light to the toolkit of light-based chips, University of Twente researchers have pushed the boundaries of the technology. This opens up the possibility of ...

Computing Sound Waves Could 3D-Print Implants Inside Your Body Ultra high-frequency sound transmits energy through flesh and other materials that block light or heat used in conventional 3D printing.
