Sentences with word «photon»

So far, international teams of scientists observed the interaction of a single or many atoms with photons in a light cage.

Because the molecules are so complex, there are many possible transitions, each emitting photons of a specific frequency.

We were not meant to be bombarded by that many high energy photons shooting directly into our eyes for such long periods.

Currently, this involves sending single photons using an optical fibre.

In this case, as we are talking about heat, we are talking about energy in motion carried by photons as gravitational energy that travels at the speed of light.

Solar cells convert the sun's energy into electricity by converting photons into electrons.

However, the researchers claim to have found a way to slow photons which, they suggest, seems to be permanent.

When photons pass through or reflect off of something, they give that object momentum.

Other quantum systems use photons for long - distance interactions.

A NEW kind of laser that powers up by freezing light in its tracks could lead to computers that run on photons, instead of electrons.

Normally when two light beams cross each other the individual photons do not interact or alter each other, as two electrons do when they meet.

Here, tiny particles of light called photons appear to change form at random.

The light photons travel differently through tumors than through normal tissue.

The infrared photons emitted by the surface are mostly absorbed in the atmosphere by greenhouse gases and clouds and do not escape directly to space.

More recently, physicists have shown that this interference pattern occurs even when the light source is so dim that single photons pass through the apparatus one at a time.

Because photons have no electric charge, they shouldn't notice one another's presence.

The difference in the energy is determined by the properties of the molecules, and thus the scattered photons carry a unique fingerprint of the substance.

No X-ray photons can ever follow the path that leads them to a detector.

Why don't photons get absorbed by all the other water vapor molecules to cause warming?

This means that the detector should be able to accurately measure single microwave photons.

That is because they can use only photons within a certain range of wavelengths to excite electrons.

The longer the journey, the fewer photons make it through intact, eventually preventing accurate transmissions of quantum keys.

In the 1940s, experiments showed that humans who have adjusted to the dark could detect as few as a half dozen or so photons.

A subsequent change in energy states as exchanges are made in potential produces photons and, therefore, light.

Until recently, there hasn't been a method for producing a beam of such energetic photons.

, which are caused by very high energy gamma - ray photons from cosmic sources smashing into the atmosphere.

However, where photons would fail, gravitational waves can succeed!

From the behavior of the measured photons the physicists verified that hyper - complex rules were not needed to describe the experiment.

A key problem with solar cells is that they only capture photons of certain wavelengths.
