A laser-equipped research platform has, for the first time, photographed airflow just millimeters above ocean waves, ...

An international research team led by the Helmholtz-Zentrum Hereon has, for the first time, succeeded in visualizing and ...

The vertical distance between the crest and the trough tells you the wave's height. ... When the moon, rather than the wind, tugs on the ocean's surface, tidal waves form.

Rogue waves - enormous, spontaneous surface waves in the open ocean - were once the tall tales of sailors. ... Oh, and when they combine trough-to-crest they cancel out.

From the geometry of trochoids, surface water particles at the troughs on either side of the crest of a secondary wave will close up when this wave is riding on the crest of a primary one, and ...

Investigate the motion of waves in water, what happens when waves get reflected and different types of superposition of waves with this guide for KS3 physics students aged 11-14 from BBC Bitesize.

Deep waves as seen from space. Deep currents as sensed from two miles under Antarctic waters. Both are rewriting what we know of the movement of oceanic waters.

It’s instructive, though, that even the trough of this wave is not very low; ... This, for me, is the crest of the current wave. Published - October 31, 2014 09:38 am IST. Read Comments .
