But the low - frequency waves generated by giant landslides are occasionally hidden in the mix of seismic vibes rumbling through Earth's crust, too, he notes.

Not exact matches

Waves from binary supermassive black holes oscillate slowly compared with supernovas, which generate high - frequency wWaves from binary supermassive black holes oscillate slowly compared with supernovas, which generate high - frequency waveswaves.

During REM sleep, the brain generates high - frequency waves of electrical activity and the eyes flicker; in humans, REM is closely linked to dreaming.

Therefore, when an acoustic or mechanical wave contacts the material, it perturbs it, generating the unique properties that block sound waves and mechanical vibrations of certain frequencies from passing through.

Parts of the string then emit low - frequency radio waves that accelerate the surrounding plasma into generating a burst of gamma rays.

These waves, known as surface - gravity waves, do not travel nearly as fast, far, or deep as acoustic - gravity waves, yet under the right conditions, they can generate the powerful, fast - moving, and low - frequency sound waves.

Pmagn Can super storms like this generate low frequency seismic waves or pressure pulse that trigger seismic activity locally and remotely?

In conventional ultrasound machines, the resulting heat causes the lens to expand rapidly, generating high frequency vibrations that produce ultrasound waves.

Infrasonic waves, with frequencies much lower than an audible voice, can be generated by sources as diverse as volcanoes, earthquakes, rocket launches and meteor air blasts.

Through MRE, a device placed on the body near the tissue being tested uses vibration to generate low frequency sound waves that pass through organs that have varying degrees of elasticity.

The ARM method, on the other hand, uses a gentle acoustic wave generated by a similar power as ultrasound imaging and at a lower frequency.

So the relatively gradual onset of slip in the Gorkha event explains why this patch, which experienced a large amount of slip, did not generate many high - frequency waves.

The magnetic field compresses the metamaterial, but does not constrain it, enabling an acoustic or mechanical wave to perturb the material and generate unique properties, including negative modulus and negative density that blocks sound waves and mechanical vibrations of certain frequencies from passing through.

Because the waves are generated by and pass through different sections of the sun, the wave frequency reveals clues about the inside of the sun and allows scientists to chart changes in the star's life.

A ceiling - mounted microphone detects low - frequency noise and the system then generates out - of - phase frequencies — the sound waves cancel each other out.
