Sentences with phrase «waves at high frequencies»

It's also still unknown whether any other bursts have twisted waves at high frequencies — the smoking gun for strong magnetic fields.

Not exact matches

Ultrasound is a common test during pregnancy that uses high frequency sound waves to look at the anatomy and structures of the developing baby.

At the TU Vienna, a complementary method was developed: not only a higher - frequency wave is added to the laser pulse, but also a lower - frequency one.

The researchers used the state - of - the - art nanofabrication technology to make arrays of electrodes with a width of only 100 nanometers (0.00001 centimeters) to excite sound waves at an unprecedented high frequency that is higher than 10 GHz, the frequency used for satellite communications.

At a high enough electron density, each cloud reflects high - frequency radio waves like a mirror.

Some of the most exotic objects in physics, such as evaporating black holes, cosmic strings and even possible extra dimensions, would induce gravitational waves at much higher frequencies than we can currently detect.

But if there are astrophysical events that produce gravitational waves at frequencies too high for LIGO to spot, their memory signals might fall easily into the observatory's detection range, thus allowing us to pick them up.

More powerful computers will allow her to use more of the high - frequency content of earthquake waves, the part that is best at illuminating shallow structures like ULVZs.

Ultrasound waves are produced by firing sound waves at a glass surface or «lens» to create high - frequency vibrations.

The research shows that when the liquid is ultra-thin — at nano and sub-micro depths — it flows away from the high - frequency sound waves.

Now the Holometer is taking data continuously, and with an hour's worth of data, physicists were able to confirm that there are no high - frequency gravitational waves at the magnitude where they were searching.

Learning more about this effect may make it possible to identify new metal oxides that can absorb EM waves at even higher frequencies.

Now Geoffroy Lerosey of The City of Paris Industrial Physics and Chemistry Higher Educational Institution in France has created a lens he says can boost resolution further using only resonance — boosting waves using materials vibrating at similar frequencies.

The prototype device built by Huang and his colleagues creates a high - frequency sound wave traveling at an angle to liquid flowing down a tiny tube.

Its three very high - frequency band radar sites in Texas, Arizona and Alabama ping the heavens with radio waves at wavelengths between 1 and 10 metres and their reflections enable us to detect objects down to the size of a basketball.

The spacecraft is moving away at high speed, and this stretches out the wave, reducing its frequency — an effect known as Doppler shift.

Low frequency waves are better received at high altitudes and in dry climates, as this reduces the amount of noise.

The distorted sound wave also contains extra energy at high frequencies.

Ultrasounds work by directing high - frequency sound waves at internal organs.

It's rigged up in a do - it - yourself manner so sound waves oscillate from the highest to lowest frequencies perceptible to the human ear through a circle of the upturned speakers, each piled up with crystals that reverberate at various frequencies.

If the wind field contains energy at the inertial frequency or higher (daily and six - hourly cases), then Vortex Rossby waves and near inertial waves are excited as ageostrophic expression of the vigorous eddy field.

Millimeter waves have greater speed capabilities because of their shorter signal wavelengths, broadcasting at much higher frequencies between 30 GHz and 300 GHz — a stark contrast to the current 3G and 4G signals that are broadcast below 6 GHz.

Named the MoVR system, it uses high - frequency radio signals called millimeter waves, pushing out data to the VR headset at speeds in the Gbps range.
