The researchers applied the higher resonant radio frequency ... s pure motion — a sloshing back and forth, similar to sound waves. “For the first time, we can take pictures of this substance ...

NASA created a haunting audio clip of sound waves rippling out of a supermassive black hole, located 250 million light-years ...

Scientists have unlocked a previously unseen behavior of acoustic waves, opening up new possibilities for cutting-edge ...

The jet of radio waves is the biggest ever detected so early in the history of the universe, astronomers reported Thursday.

THE recent discovery of solar radio noise, in the range 30-1,000 megacycles ... will produce electromagnetic radiations the maximum wave-lengths of which are comparable to stellar dimensions.

The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM ...

By containing the sound wave on the surface of a chip ... defense systems and even radio astronomy. More information: Govert ...

For water waves and sound waves the unit hertz is usually good enough but radio and TV waves have such a high frequency that the kilohertz (\(kHz\)) or even the megahertz (\(MHz\)) are better units.

At double the width of our Milky Way galaxy, this jet of radio waves is the biggest ever detected so early in the history of the universe, astronomers reported Thursday. Radio jets like this are ...
