Sentences with phrase «smaller than visible light»

Not exact matches

Stereocilia are extremely small, less than a half a micrometer in diameter, which is about the wavelength of a visible light.

The idea is to blot out the light of a star and zero in on a small planet, right next to it in the sky and 10 billion times fainter (at visible wavelengths) than it.

Because the beads are only about 100 nanometers across, slightly smaller than a wavelength of visible light, the collection diffracts light, making the gel shimmer with an iridescent glow.

Producing a cloak to hide objects from visible light, which has a wavelength several orders of magnitude smaller than microwaves — let alone cloaking objects when viewed from any direction — seemed a more remote possibility.

By adjusting the width of the honeycomb cells to make them much smaller in diameter than the wavelength of visible light, the researchers kept the coating from reflecting light.

«Meta - lens works in the visible spectrum, sees smaller than a wavelength of light: High efficiency ultra-thin planar lens could replace heavy, bulky lenses in smart phones, cameras and telescopes.»

Making metamaterials for shorter wavelengths such as visible light is more difficult because it entails making elements much smaller than a micron, approaching the sizes of components on modern computing chips.

Fabricating a device that captures optical wavelengths in the same way will not be easy, as visible light has a wavelength orders of magnitude smaller than that of microwave radiation.

Known as the Abbe diffraction limit, it meant that a researcher using visible light — the best method for studying biological samples — couldn't hope to see things smaller than about 0.2 micrometers, or millionths of a meter.

Normally visible light could not pick out the lines because the spacing between them — 150 nanometers — is smaller than the light's wavelength.

Scientists at The Australian National University (ANU) have designed a nano crystal around 500 times smaller than a human hair that turns darkness into visible light and can be used to create light - weight night - vision glasses.

Doing the same thing for smaller visible wavelengths is harder, because the metamaterial elements must be made smaller than the wavelength of the light.

When these spirals are shrunk to sizes smaller than the wavelength of visible light, they develop unusual optical properties.

«Particles of any kind, even much smaller than the wavelength of visible light, will, as a rule, make the sky brighter but at the expense of its purity of color,» Bohren says, noting that the effect is more pronounced when there is a high concentration of large aerosols.

With much shorter wavelengths than photons of visible light, electron beams can be used to observe objects hundreds of times smaller than those that can be resolved with an optical microscope.
