I kept getting a series of low-frequency waves that were like nothing I'd ever seen before.

They turned down my request to follow up research on those low-frequency waves.

Such work suggested that many tsunami earthquakes put a great amount of energy into low-frequency waves.

The search radar was powerful, but like all of its type it also transmitted low-frequency waves, and those were easily jammed.

His ear tendrils caught the low-frequency waves of whistling.

Researching various government experiments, Gilligan discovered the controversial use of low-frequency waves.

But you can also make ELF, extremely low-frequency waves, which are long-each individual wave is maybe twenty feet long.

The attendant dispersion is a necessary consequence of the energy dissipation and causes the high frequency waves to travel faster than the low-frequency waves.

The low-frequency waves of an earthquake are amplified by the mud of the lakebed, which in turn, is amplified by the building itself.

A slow vibration creates low-frequency waves which we hear as a low-pitched noise, while a fast vibration produces a high-pitched noise.

But this..." Jordin stared at the video feed, then looked over at the multiple screens that showed the sources of the low-frequency waves they were receiving.

He obtained a PhD in physics from Imperial College London with a thesis on the theory and data analysis of low-frequency waves in the Earth's space environment.

Because earthquakes and tsunamis generate low-frequency waves, O'Connell-Rodwell and other elephant experts have begun to explore the possibility that the Thai elephants were responding to these events.

Into the theoretical ferment, the Los Alamos scientists are now adding the secret acoustic recordings made on the ground by the military during the cold war, readings that are inherently more thorough than the space-based ones, since detecting sound waves and inaudible low-frequency waves is easier than recording distant flashes of light.
