EM waves are 'transverse' waves. This means that they are measured by their amplitude (height) and wavelength (distance between the highest/lowest points of two consecutive waves). The highest point ...

Space might seem calm when gazing up at the night sky, but invisible waves ripple continuously through the universe, bending ...

Seismological research is directly related to the incubation, occurrence, and evolution of earthquakes. Scientists seek to ...

In a new Physical Review Letters study, researchers have successfully followed a gravitational wave's complete journey from ...

Researchers have mathematically elucidated how the presence of crystals and gas bubbles in magma affects the propagation of seismic P-waves. A novel equation was derived to describe the travel of ...

A sound wave is a vibration that travels through a solid, liquid or gas such as the air or water. A loud sound has a large amplitude, a high pitched sound has a high frequency. Musicians and ...

And demodulation is practically the exact opposite, where the message signal is extracted from the carrier wave and used. In this article, we are going to learn about modulation and more about ...

Abstract: Propagation of arbitrary-amplitude ion-acoustic solitary waves (IASWs) as well as ion-acoustic periodic waves (IAPWs) is investigated in a fully degenerate quantum electron-ion plasma ...

Abstract: A 2-D matrix ultrasound array is used to monitor acoustic radiation force impulse (ARFI) induced shear wave propagation in 3-D in excised canine muscle. From a single acquisition, both the ...
