The inner most lay of the Sun is known as “the core.” The core of the Sun helps to begin the generation of heat and light, which feeds the Earth’s life. The inner most portion of the sun has the highest temperature and the most pressure. Based upon the category of the Sun in the stellar classification, it is made up of hydrogen and generates energy from nuclear fusion. Nuclear fusion reaction is “when two or more small light nuclei combine to form a larger nucleus,” (Young, 2012). The hydrogen atoms perform nuclear fusion and form a helium atom, but how does this happen? There are several sets nuclear reactions that occur before the helium atom is formed, also known as the proton-proton chain reaction.
“1. Two protons combine to form a deuterium atom (hydrogen atom with one neutron and one proton), a positron (electron with a positive charge) and a neutrino. 2. A proton and a deuterium atom combine to form a helium-3 atom (two protons and one neutron) and a gamma ray.

- When we look up into the sky, what do we see. During the day, we often will find the sun. The sun is much more than a ball of fire that we see in our daily lives. The sun gives earth life, from the condition of the season to the life that is produced. Overall, when we think of the sun we think of heat and light but one might question; how does the sun produce the heat and light that is necessary for earth to sustain life. The sun is also known as a star, just like the stars we see at night that illuminate the night sky.... [tags: temperature, hydrogen, nuclear fussion]

- How the Sun Produces Light and Heat. The sun is a star that is medium sized among the star categories. Solar system is pivoted around the sun. The sun is a primary source of light and heat for earth which is responsible for keeping the temperature of earth in a reasonable range that is sustaining life. There has been considerable debate on the source of heat and light that the sun emits. In 1850s scientists believed that the when gravitational force is converted into heat energy a light is produced.... [tags: nuclear reactions, fusion, stars]

- Hopefully we all know how important the Sun is to us. However, some often forget why that is. The Sun is the star at the center of the solar system and is the most important star for the living and non-living organisms on Earth do to the fact that it provides the light energy and the heat needed to support life. Without the heat and light that it provides, the Earth would be lifeless and a ball of ice. The sun was created in a vast cloud of gas and dust over five billion years ago. . Over a period of many millions of years, this gas and dust began to fall into a common center under the force of its own gravity.... [tags: Energy, Sun, Nuclear fusion, Light]

- Urban Heat Islands For more than 100 years, it has been known that two adjacent cities are generally warmer than the surrounding areas. This region of city warmth, known as an urban heat island, can influence the concentration of air pollution. The urban heat island is formed when industrial and urban areas are developed and heat becomes more abundant. In rural areas, a large part of the incoming solar energy is used to evaporate water from vegetation and soil. In cities, where less vegetation and exposed soil exists, the majority of the sun's energy is absorbed by urban structures and asphalt.... [tags: essays research papers fc]

- LIGHT: A FUNDAMENTAL FORCE IN OUR WORLD If asked what light is, one could say that it's one of the most basic elements of our world and our universe as we perceive it. It is through sight that we receive 90% of our information. It is through the use of telescopes aiding the naked eye that we are aware of the heavenly bodies around us. It is through light that the energy from the sun is transferred to us. The sun's energy supports the food chain; plants use it to turn water and CO2 into energy usable by other organisms....

- The Luminescence of Black Light Black Light. What is it. It is a portion of the Ultra-Violet Spectrum that is invisible to our eyes. We can not distinguish it. However, when this radiation impinges on certain materials visible light is emitted and this is known as "fluorescence." Fluorescence is visible to the human eye, in that it makes an object appear to "glow in the dark." There are several sources of ultra-violet light. These sources are: the sun, carbon arcs, mercury arcs, and black lights.... [tags: essays research papers]

- Solar Photovoltaic Cells Solar energy is a general term referring to any process that turns sunlight into energy. Two common forms of solar energy are used today: Solar photovoltaic cells and solar thermal technology. Solar thermal technology uses the heat generated from sunlight to create energy. Most commonly, this can be used to heat water for a house or other projects. Or, with increasing complexity, it can turn the heat into electricity. Unfortunately, much of this technology is too expensive and complex to be practical in the United States on any large scale.... [tags: Solar Energy Heat Sun essays]

- As I lay on the minute golden grains of sand, I looked up at the brilliant sky, adorned with flashes of pink and orange and purple, mirroring the colours of a flawless seasoned apricot. The goddess-like sun’s face is being embraced by the demure navy fingertips of the skyline. The dull light of the sun somehow manages to kindle my senses in a way I had never seen or felt before. Everything felt like it came to a standstill and the effect of the light made the scene look like one in a painting. The waves break gently into white foam on the black beach....

- The firefly is sometimes referred to as a “lightening bug.” There are about 2,000 firefly species; for the most part they live in warm but humid environments. Fireflies are neither flies nor bugs; they are actually part of the beetle family. Fireflies are from the Animalia kingdom, and are of the Lampyridae family. Fireflies hibernate over winter by burrowing underground, under water or settle under the bark of a tree some can live for several years by hibernating as larva during the winter. Most everyone knows how the fireflies got their name; the firefly produces light through a bioluminescence chemical reaction that allows them to glow however, fireflies in the western Untied States lack...

- How power produced by a solar cell is affected by its distance from a light source. Theory I expect that as the solar cells are moved closer the light source the higher the power they will produce. As light moves away from the source it spreads out at all angles the further you are from the source the less intense the light will be. P = I V Power = current x volts P = FA Power = flux x area Flux = P/A Area of 4 solar cells that I will use is 0.0077m2 This means that the higher the flux the higher the power as we are not changing the area of the solar cells as this remains is constant....

In addition to the nuclear fusion reactions take place, energy is being produced from mass in that E=mc2, so the energy in turn will help to produces an outward pressure and the inward pressure is produced by a gradational attraction to help keep the sun stable motion (“The Life-Giving Sun”, 2002). During the fusion reaction, not only is a larger atom produced but the high energy photon gamma rays are produced. The gamma ray photon is given off the decay of beta particle during the second phase of the reaction, similar to (n p + ß- + ve). After the decay occurs it will leave the nucleus in an excited state which can then decay to a grounded state by emitting a photon gamma ray (Young, 2012).
The next layer of the sun is known as the radioactive layer which is the first part of the solar envelope, and “accounts for 45% of the sun’s radius,” (Layton and Fruedenrich, 2000). The photon gamma rays leave the core of the sun and travel through the radiation zone by way of electromagnetic radiation. The radioactive layer is often cooler that inner core of the sun, it is here that photons can reproduce in a sense. When the photon is released, it is absorbed by a gas molecule, heated and then reemits another photon of the same wavelength, as photons are absorbed and dispersed each cycle take a significant amount of time (Layton and Fruedenrich, 2000). The photon production is important but movement of the photons occurs with the use electromagnetic wave, the movement of waves circulates through space from one region to another (Young, 2012). The circulation of light is described by the wave, photons move along an electromagnetic wave which carries the energy. The movement of the photon is known as electromagnetic radiation in that electrical charge in an accelerated motion caused by the high temperature within the sun (Young, 2012). At the high temperatures within the radiative layer of sun allows the visible light to appear. The movement of the photon is known as electromagnetic radiation in that electrical charge in an accelerated motion caused by the high temperature within the sun. The equation E=cB and c=1/√(Ɛoµ0) can be applied because the energy carrying waves and “the electromagnectic wavees propagates the photon particles traveling through space carrying the emitted radiant energy,” (“Electromagetic radiation,” 2014).
