The human ear detects sound. Sound waves enter the ear canal and cause the eardrum to vibrate. Three small bones transmit these vibrations to the cochlea. These bones transmit most efficiently ...
Light is a type of electromagnetic radiation that can be detected by the eye. It travels as a transverse wave. Unlike a sound waves, light waves do not need a medium to pass through, they can ...

Researchers make sound waves travel in one direction only, with implications for electromagnetic wave technologyIn 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.
Researchers at the University of Twente have solved a long-standing problem: trapping optically-generated sound waves in a ...

We say a message is incoherent when we can't make it out, or when it doesn't make sense. A scribbled note, a drunken argument ...
Thousands of marine species from microscopic zooplankton to the largest cetaceans rely on sound for survival and many have evolved unique oral and aural adaptations. Understanding them better could ...
So-called Rayleigh–Bloch waves can release enormous amount of energy that can damage technical systems under certain circumstances. They only exist below a precisely defined cut-off frequency; above ...
We've talked about what sound waves are, now let's establish why they ... Pink noise is best for: People who are light sleepers. Try it: Check out Honeywell's Dreamweaver Sleep Fan, a small ...
Researchers at the University of Bayreuth have developed a method that makes objects on a magnetic field invisible within a ...
This particular snow was light and fluffy, a perfect sound absorber. When the ground is covered with fresh, dry, fluffy snow, sound waves are absorbed into all the air pockets in the snow ...
