Sentences with phrase «than visible light»

Because electrons have a much shorter wavelength than visible light, they can illuminate the structure of tiny objects.

It is primarily used to study infrared rays — slightly longer than visible light — from young stars and distant galaxies.

However, infrared - light sources, elements and detectors tend to have inferior performances and be more expensive than their visible light counterparts.

UV radiation has a shorter wavelength and a higher energy level than visible light, while IR radiation has a longer wavelength and a weaker energy level.

But perhaps there are cases where the radiation comes out in the form of X-rays or gamma rays, he says, rather than the visible light astronomers normally look for when searching for supernovae.

Very large antennas are necessary to precisely determine the position of radio sources because radio waves have much larger wavelengths than visible light waves, and because the detection of any object in space depends largely on the size of the observation instrument (that is, its lenses, mirrors or radio antennas).

Before the MAGIC measurement this radiation was believed to stop abruptly when the photons reach a energy few billion times larger than visible light.

Infrared radiation passes through interstellar dust much more easily than visible light, so by looking at the infrared light from a galaxy we can learn about the new stars forming within the clouds of dust and gas.

Called shortwave infrared, it penetrates skin and other tissue more deeply than visible light or the near - infrared light used in current imaging methods.

«X-rays are used to study the nano world, as they are able to show much finer details than visible light and their penetrating power allows you to see inside objects,» explains Bajt.

Even so, the principle is the same: hit it either with photons (but now with those having much more energy than visible light photons) or any of the enormous zoo of particles discovered by high energy physicists.

It is designed to detect gamma rays tens of billions to tens of trillions times more energetic than visible light.

The short wavelength of an electron beam enables much higher resolution and magnification than visible light.

For the same reason, infrared astronomy enables researchers to observe cosmic objects through large clouds of interstellar dust that scatter infrared radiation substantially less than visible light.

3.4 billion years ago — First photosynthetic bacteria They absorbed near - infrared rather than visible light and produced sulfur or sulfate compounds rather than oxygen.

The light used in the experiment has a considerably longer wavelength than visible light: It is radiation in the terahertz - or infrared regime, with a wavelength of about a tenth of a millimetre.

The process is similar to what lights household fluorescent bulbs, except that the supernova remnant glows in X-rays rather than visible light.

After the serendipitous discovery of radio waves coming from the Milky Way's center in the 1930s, scientists realized radio waves, which have a longer wavelength than visible light, could reveal many aspects of cosmic phenomena not visible in other wavelengths.

Those unique properties have proven conducive to working with THz light waves, which have longer wavelengths than visible light and therefore require new imaging technology.
