Sentences with phrase «because radio waves»

Radio telescopes are large — over 100 meters in diameter and beyond — because radio waves contain such a small amount of energy.

Not exact matches

Because you have to use a radio wavelength that is smaller than the dimensions of the object you are trying to locate, radar relies on high - frequency waves, just a few inches long (higher frequencies have shorter wavelengths).

This «beam - forming» capability makes the antennas crucial to ultrafast wireless applications, because they can focus a stream of high - frequency radio waves that would quickly dissipate using normal antennas.

The Milky Way's black hole, Sagittarius A *, is clearly sucking in hot gas because doing so makes it burp out radio waves that we can detect.

From Earth, they appear to pulsate because the beams of radio waves they emit from their poles sweep past the Earth with every revolution.

And just as we can regard radio emissions as waves and not as photons because of their long wavelength, the gravitational waves that we detected were of sufficiently long wavelength that we could indeed regard them as waves.

Most SETI researchers look for signals sent by sentient beings in radio waves, because these waves traverse galaxies without interference from gas and dust.

Pulsars reveal the magnetic field in neighboring reaches of space because they typically emit polarized light — radio waves that vibrate in a particular plane as they travel through space.

This is because land - based networks rely on radio waves, which work well in the air, but not so much underwater.

Blandford: Well, if we just go outside of the surface of the Earth, the first place we find it is in the ionosphere, and one of the reasons that we can bounce radio waves off the ionosphere is because there is plasma there.

The scopes picked out thousands of these silicon monoxide clouds, which they liken to lasers because they emit radio waves as bright pinpoints.

«Because the radio telescopes are placed far apart at sites all round the world, they detect the radio waves at different times,» explains Dr. Mikko Kotiranta, a researcher at Fraunhofer IAF.

Alien hunters look for radio waves because humans are so fond of using them.

Because the jet features are moving toward Earth at almost the same speed as the radio waves they emit, they can appear to move across the sky at faster - than - light speeds.

Pulsars twinkle at a set rate that scientists can measure because they emit two jets of radio waves in opposite directions while itself spinning along a different plane, causing the jets to spin like a spotlight.

The pulsar's rotation is thought to slow because the neutron star's powerful magnetic field acts as a giant dynamo, emitting light, radio waves and other electromagnetic radiation as the star rotates.

In addition, because the atoms emit at a very specific wavelength, the scientists could detect the galaxy's rotation by tuning the telescopes» radio receivers to receive radio waves whose length has been changed by Doppler shifting.

Because the molecules emit radio waves at specific frequencies, shifts in those frequencies caused by motions (called Doppler Shift) can be measured, revealing the direction in which the gas is moving relative to Earth.

The VLA can image the gas in such galaxies because it is particularly sensitive to the radio waves naturally emitted by hydrogen atoms.

Jupiter gives off radio waves because it's still cooling off from its birth about 4.6 billion years ago.

Honda used IR technology rather than radio waves because many Japanese traffic lights already have IR transmitters, and the government plans to overall and expand the V2I transmitters within the next two or three years.

Because the ionosphere has a different refractive index from the layers above and below it, radio waves are «bent» (refracted) as they pass from one layer to another.

This modification of the ionosphere makes GPS less accurate and can even lead to a complete loss of the signal because the ionosphere can act as a lens or a mirror to radio waves traveling through it.
