This is a nuclear reactor starting up Why does it glow blue? It's the Cherenkov radiation: 'Cherenkov radiation is electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium at a speed greater than the phase velocity of light in that medium.' It's going faster than the speed of light (in water).

The Scientific Reason Behind Neptuneâs Blue Color The main reason behind Neptune’s blue color is methane. When sunlight hits the planet’s surface, the methane clouds absorbs the red end of the spectrum of visible light. The blue end of the spectrum gets reflected back.o, when we see the bright bluish color of Neptune, we actually see the reflected sunlight, minus the red light. Neptune looks like a beautiful blue sphere from a distance, but the color variations in its clouds can be clearly noticed, if viewed closely. The surface of Neptune is also well-known for powerful storms.

- We need to start with the fact that white light is a combination of all colors produced equally by a glowing object. A glowing object that appears blue is blue because it's producing more blue light than it is producing red, orange, yellow, green light. The color of a glowing object depends on the temperature of the object. Now we can proceed to your question. Two Reasons why the Sun appears yellow:

- Incandescence is a high-energy process for emission of light. Historically, the first glow in the dark watches used radium paint. The radium decays by emission of an alpha particle. An alpha particle has 2 protons and 2 neutrons with no electrons. The emission of the alpha particle alone does not produce visible light.ncandescence is a high-energy process for emission of light.

U.S. Energy Information Administration - EIA - Independent Statistics and Analysis Nuclear power reactors do not produce direct carbon dioxide emissions. Unlike fossil fuel-fired power plants, nuclear reactors do not produce air pollution or carbon dioxide while operating. However, the processes for mining and refining uranium ore and making reactor fuel all require large amounts of energy.

What is Cerenkov radiation? Water is intrinsically blue because of its selective absorption of the red end of the spectrum. One explanation of the Cerenkov effect in water is that the atoms in the water become excited by the Cerenkov shock wave and then de-excite, emitting blue light. Another possible explanation is that the number of photons emitted by such a charged particle is inversely proportional to wavelength.

- I didn’t think it could be true. We ate at the restaurant and when the sun went down, we took off on a boat into the night. A few minutes later, you could see schools of fish glowing greenish-blue in the water. I put my hand in the water and that made it glow as well. Our guide suggested diving in and swimming around.

- DAVID POGUE: In a reactor, one neutron splits a uranium atom, which releases energy and two or three more neutrons, which, in turn, split more atoms, releasing more neutrons and so on, causing a chain reaction. MATTHEW DENNIS: So you get more and more neutrons, and thus, the chain reaction keeps going.

Why is the hottest flame blue? There are two main contributors to the color of a flame. The one that probably impacts the blue=hot most is Black-body radiation. The hotter the object's temperature, the bluer the emitted light is. Another major contribution is emission from electron transitions. It emits light in specific energies.

Why is Uranus blue? Because of this, its poles are sometimes pointed almost directly at the Sun. Uranus' atmosphere is made up of hydrogen, helium, and methane. The temperature in the upper atmosphere is very cold. The cold methane gas is what gives Uranus its blue-green color.The rapid rotation of Uranus causes winds up to 600 kilometers per hour to blow in its atmosphere.Uranus has eleven known rings which contain dark, boulder-sized particles. Uranus has 27 named moons.he temperature in the upper atmosphere is very cold. The cold methane gas is what gives Uranus its blue-green color. The rapid rotation of Uranus causes winds up to 600 kilometers per hour to blow in its atmosphere. Uranus has eleven known rings which contain dark, boulder-sized particles.

What Causes Bioluminescence? Bioluminescent organisms can glow in complete darkness. They contain a unique compound called luciferin, according to scientists who study bioluminescence at the University of California at Santa Barbara. When luciferin is exposed to oxygen, a chemical reaction (aided along by an enzyme called luciferase) emits light. Bioluminescence is different from fluorescence. Fluorescent organisms, such as butterflies that have fluorescent markings on their wings, would not glow in complete darkness. Fluorescent pigments only glow in the presence of an external light source, according to the UCSB scientists.

Nuclear reactor A nuclear reactor, formerly known as atomic pile, is a device used to initiate and control a sustained nuclear chain reaction.he heavy nucleus splits into two or more lighter nuclei, (the fission products), releasing kinetic energy, gamma radiation, and free neutrons. A portion of these neutrons may later be absorbed by other fissile atoms and trigger further fission events, which release more neutrons, and so on.

- The bioluminescence is the result of a chemical reaction similar to that of a glow stick, which gives the waves a stunning blue-green glow when disturbed. —

Plutonium Some of the plutonium-239 in the fuel rods burns (fissions) along with uranium and helps produce heat, which is converted into electricity. As fission continues, the reaction products remain in the fuel pellets and absorb neutrons, slowing (poisoning) the fission process.

Cause The test. An inactive nuclear reactor continues to generate a significant amount of residual heat. RBMK reactors, like those in use at Chernobyl, following an emergency shutdown will continue to emit 7 % of their thermal output and therefore must continue to be cooled.

- Rods inserted among the tubes holding the uranium fuel control the nuclear reaction. Control rods, inserted or withdrawn to varying degrees, slow or accelerate the reaction. Water separates fuel tubes in the reactor. The heat produced by fission turns this water into steam.

How Nuclear Power Works Because uranium atoms are so large, the atomic force that binds it together is relatively weak, making uranium good for fission. In nuclear power plants, neutrons collide with uranium atoms, splitting them. This split releases neutrons from the uranium that in turn collide with other atoms, causing a chain reaction.This chain reaction is controlled with control rods that absorb neutrons.n the core of nuclear reactors, the fission of uranium atoms releases energy that heats water to about 520 degrees Farenheit. This hot water is then used to spin turbines that are connected to generators, producing electricity.

Why snow is white but glacier ice is blue Glacier Ice is blue because the light that enters the glacier ice travels much farther in the ice than it did in the snow. This gives the ice time to absorb more red than blue light. So when the light returns to the surface, it is lacking red light, making it appear blue. This is a photo from an email of iceberg photos that Deb sent to me.
