Difference Between Diphenyl Oxate And Glow Sticks

This occurs when a product is generated in the excited state and then relaxes to the ground state in which a photon is emitted. When the electron relaxes, energy is released as a vibration and heat. Electrons in the same orbital are paired and must have opposite spins. There are two types of electronic states: singlet and triplet. In a singlet state, the spins of all of the electrons are paired while in a triplet state, the spins are flipped or unpaired. Phosphorescence and fluorescence occurs when electrons relax from the singlet and triplet states and emit visible light. Fluorescence emits light at a longer wavelength than it is absorbed. This process is rather fast as the light appears to be a blue-green color. Phosphorescence is very similar to that of fluorescence. However, in phosphorescence there is longer interval between the excited and ground states since the flipped spin has to flip back. This flipping of spins requires energy which leads to a less energetic triplet state compared to that of the singlet state. The longer interval in phosphorescence also sometimes results in a red color and a longer excited state period. Chemiluminescence also has other usages such as its ability to identify when blood is present. The luminol turns blue-green when the alkaline solution is exposed to

Solids and liquids glow at very high temperatures. To see these glow, you need to look at using a spectroscope. When you do look through the spectroscope, you see a band of colors that resembles a rainbow. The reason why this happens is because the atoms are packed closely together. In the early 1900’s, Niels Henrik David Bohr created an explanation why the lines of the spectrum are the way they are. Niels Bohr was a Danish born physicist who is world renowned for his works of quantum physics. Bohr proposed that electron that orbits the cloud of protons and neutrons has a set to have a certain energy. When the electron occupies the energy level of lowest energy, it is in its ground state. If an electron occupies a higher energy levels then

Even in the darkest conditions there are tiny bits of light even if your eyes can't see it they are there. Night vision goggles are a good example of letting you see the light. How do they let you see this light? Why is it green?

Not only that, but the unique element actually glows a bright red-ish orange when it is electrified... At least, typically. Depending on the gas, chemicals, and how it is electrified, the element can also glow other colours such as red, yellow, white, and blue!

Bioluminescence has been utilized by a variety of organisms for thousands of years. Within this time period, bioluminescence has been through a series of evolution making it unique to the organism that utilize them. Although the specific biochemical components and pathways tend to be varied among species, most bioluminescent processes involves a substrate and an enzyme known as luciferin and luciferase. The substrate Luciferin is a compound that tends to undergo through oxidation and is the source of light of most bioluminescent organism. Luciferase on the other hand is an enzyme that catalyzes luciferin. In most species luciferin and luciferase are housed in the light producing components of the organism. These molecules are mixed together along

Fireworks produce three conspicuous forms of energy: bright light, heat, and a huge release of sound. The colors that we see are created by heating metal salts, like sodium nitrate or calcium chloride, that produce certain colors. The atoms of each element absorb energy and release it as light of specific colors. This happens because when an atom absorbs energy it rearranges its electrons from the ground state, up to an excited state. The ground state is when the electrons are in their lowest-energy state. The excited

The Aurora Borealis also known as “Northern Lights”, are bright lights that appear when the sun's temperature rises. When the temperature rises and the sun begins to overheat it releases oxygen and nitrogen. Oxygen and Nitrogen are the key factors that gives you the colors that are associated with the lights. “The colors most often associated with the aurora borealis are pink, green, yellow, blue, violet, and occasionally orange and white. Typically, when the particles collide with oxygen, yellow and green are produced. Interactions with nitrogen produce red, violet, and occasionally blue colors.” (SPACE.com Staff 3). This quote gives us a little more information about what colors are present, and how they are formed. You can mainly see these

Red is produced by strontium salts and lithium salts. Incandescence is light produced from heat. Heat causes a substance to become hot and glow, initially emitting infrared, then red, orange, yellow, and white light as it becomes increasingly

It’s candle making time once again! I’m always ready for a fun DIY candle project. The one I have in mind for today is incredibly versatile; you can make your candle scented or unscented, and you will choose the hues you want your candle to be. Once you’ve learned the fundamentals of how to make a beautifully layered candle, you may then want to experiment with different shapes and sizes, as well.

Encyclopedia Britannica tells us that the interaction between these particles is crucial to the formation of the lights.

It makes its tail glow using bioluminescence which is a chemical reaction between a chemical the glow worm makes called luciferin mixes with air. That chemical reaction gives off light.

To begin, a fuse is lit on a firework that eventually reaches metals inside a firework, providing heat to the metals. This heat causes the electrons of the metals in the firework to become excited, meaning that they gain energy and move up to a higher, unstable energy level. Because this higher level is unstable, the electrons soon fall back down to their initial energy level and release energy in the form of light as they do. This light is what we can see when fireworks are lit, but the color depends on the amount of energy released. Higher energy releasing metals like Copper (I) chloride and Strontium copper compounds yield blues and purples, while lower energy releasing metals like lithium carbonate, strontium carbonate, and calcium salts yield reds and oranges. Greens and yellow result when median energy releasing metals like sodium compounds and barium compound are

Firework colours are all about chemistry and you can create them with the help of some basic tools. The colours you create are made exactly the same way as inside fireworks!

Lasers work by using a process called stimulated emission which allows an incoming photon (of a precise level) to interact with an excited atomic electron. Stimulated emission allows three things to occur. The first is the light from a laser being monochromatic. This means that the light is of only of one specific wavelength of colour. The wavelength of light is decided by the amount of energy released when the electron drops into a lower orbit. Light can only be released when an atom has become excited and gives off an electric discharge which causes the electrons to drop form a high energy orbit into a lower energy orbit. The second is coherency; this is the organization of the light. Every photon moves in a specific time to match the others. Therefore each photon has wave fronts that take-off in unison. The third is the direction of the light. The light has a very concentrated beam and is very strong. Ordinary light do not have these properties. The light of a flashlight is very spread out and disorganized unlike the light of a laser.

Fluorescence spectroscopy, like all spectroscopic methods and instruments, involves the excitation of a sample and the measure of the sample’s response to such excitation. However, the response measured varies from what is needed to be analysis and the instrument used. For fluorescence, the sample is excited at a certain wavelength. This excitation causes the molecule to jump energy levels, from the ground to the excited state as shown in the figure below:
