We also know that photons passing through dark energy allow for the kind of energy changes that produce varying temperatures that are in turn represented in the CMB map.

It was recently discovered that photons passing within a wavelength of a water droplet can quantum tunnel into the droplet and emerge on the other side of the droplet in exactly the opposite direction.

- this is because the heat content of a cubic metre of space is extremely low, and is dominated by the photons passing through it.

Not exact matches

After shining the light beam through a crystal to entangle the photons, the physicists split the beam in two, letting half of each entangled pair pass though the cat cutout.

Some light particles, or photons, would pass through, making up an image.

Whereas classical physics insists that two light beams will pass right through each other untouched, some of the earliest predictions of QED stipulate that converging photons occasionally scatter off one another.

This is exactly what would happen if they were passing through both slits as a wave, and the two wavefronts interfered with one another, so the experiment is usually taken as evidence that photons can be both a particle and a wave.

The resulting electron - rich plasma scattered the CMB's photons as they passed through.

Bob's computer measures the photons» polarization when they pass through identical filters at his end of the fiber optic line.

In the double - slit experiment of 1908, a photon fired at a pair of slits passed through both at once and interfered with itself on the other side.

He set up his experiment to measure spin angular momentum of photons in high vacuum, with measurements based on the rotation of a two - inch diameter wave plate — a device that can alter the polarization state of light passing through it.

Unlike atoms and the matter they're made of, two photons on a collision course will simply pass through one another, with no interaction.

No matter where a packet is sent or what type of equipment it happens to pass through, one basic cycle repeats over and over until it arrives at its destination: The message is stored in a computer's memory, analyzed to see where it should go next, encoded somehow for transmission (whether it be as electrons down an Ethernet cable or as photons radioed out from a Wi - Fi card), sent along to the next computer in the chain, decoded, and then stored in the memory of that computer.

The energized atoms then emit photons as the weak laser pulse passes through the glass slabs, allowing the laser beam to pick up trillions of extra photons.

Alice passes Bob the key by encoding it in single photons, which can be polarized horizontally to signal a 0 or vertically to signal a 1.

If this were all there were to it, then Eve the eavesdropper could also read the key and then pass the photons to Bob.

No information passes from A to B, but the photon change can be used to partially encode quantum bits, called qubits.

Thus astronomers can interrogate the photons to reveal the basic physical properties, like velocity and density, of gas passing through shock waves in the jets.

The interference depends on single photons apparently going through both holes at once, but when there is no interference the photons must be passing through either one hole or the other.

The opposing beams canceled out one another, creating a light field with uniform intensity that allowed the field's photons to pass through the Styrofoam particles instead of bouncing off their surface.

This interference arises because it is not possible, even in principle, to determine which photon has passed through which hole, say quantum theorists.

But if you turned the fence 90 degrees, the vertically polarized photon would be blocked; a horizontally oriented photon would pass through.

What's less intuitive is the fact that photons fired one at a time toward two slits still demonstrate the same wavelike interference behavior after they pass through — it's as though individual photons are able to travel through two slits at once while still arriving at one location!

A photon does not pass through time at all: Traveling at the full speed of light, it experiences being everywhere in the universe all at once.

If you think of the filter as a picket fence, a vertically polarized photon would pass through a gap between two slats.

Hooper says that according to the many - worlds interpretation, the interference pattern comes about when a photon interacts with its clone passing through the other slit in a parallel universe.

The particles will pass through several of these fiber «mats» and deposit part of their energy along the way, producing some photons of light that will then be turned into an electric signal.

X-ray phase contrast imaging measures not just the number of X-ray photons that get through the sample, as in conventional X-ray imaging, but also the phase of the X-rays after they pass through, offering a complete look at interfaces inside a structure.

A higher number of layers means that the electron changes its energy states when it passes through the structure, and therefore the number of emitted photons increases.
