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 ...

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 the infinite past to the infinite future as it encounters a black hole.

backward wave amplitudes (Pb), and a reflection index (=[Pb/(forward wave amplitude+Pb)]), in addition to augmentation index, Pa, and reflected wave transit time. During a median follow-up of 15 years ...

Make waves without getting wet. With just a Slinky and your hands, model transverse wave resonances as well as longitudinal wave resonances. Learn about nodes and antinodes of motion and compression.

H s Height of significant wave (metres). This is the average height of the highest one third of the waves in the record. H max Maximum height of the waves (metres) in the record. T z Average wave ...
