Amplitude – the distance from a peak or ... The same terms can be used to describe longitudinal waves, but with a few important differences: Compression – a region of high pressure, where ...

From the dispersion diagrams thus obtained we infer the appropriate periodic length and ripple amplitude of the guiding structure that optimize the beam-wave interaction ... denotes the longitudinal ...

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

There have been rockets launching from Vandenberg for decades, so why are the Falcon 9 launches of such concern? "Because of ...

In a new Physical Review Letters study, researchers have successfully followed a gravitational wave's complete journey from the infinite past to the infinite future as it encounters a black hole.

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: The propagation properties of longitudinal dust acoustic waves (LDAWs) have been investigated in a strongly coupled dusty plasma containing negatively charged dust fluid, and nonthermal ...

Pulse pressure and pulse wave velocity, markers of arterial stiffness, have been associated with stroke, dementia, and lowered levels of cognitive function. Here we examine longitudinal relations of ...

Abstract: A new technique for a PWM inverter is described. By using a triangular wave of saturable amplitude, adjustment of the amplitude of the multiple reference waves can be avoided. Two typical ...
