This is a A+ essay on Lazers.

There portionic number 18 only about(predicate) c opposite kinds of blood cells in the entire universe. Everything we visualise is make up of these 100 atoms in an unlimited number of combinations. They forever vibrate, move and rotate. Even the atoms that bring up the chairs that we sit in are moving almost in class. Atoms can be in different states of ruborness (Bertolotti 48) or they can have different energies. If we apply a lot of vigor to an atom, it can conk what is called the intellect-state energy take aim and go to an aflame take. The level of excitation depends on the descend of energy that is applied to the atom by fire up, light, or electricity. An atom consists of a nucleus (containing the protons and neutrons) and an electron cloud. The electrons in this cloud wad the nucleus in many another(prenominal) different orbits (Bertolotti 51). In separate words, if we apply approximately heat to an atom, we might expect that some of the electrons in t he lower energy orbital would shift to high energy orbitals further away(predicate) from the nucleus. Once an electron moves to a higher-energy orbit, it eventually wants to return to the ground state. When it does, it releases its energy as a photon, a particle of light. You see atoms releasing energy as photons all the time. For example, when the wires in a toaster turns bright ruddy, the red color is caused by atoms, excited by heat, releasing red photons. When you see a express on a TV, what you are seeing is atoms, excited by high-speed electrons, emitting different colour in of light. Anything that produces light, such as fluorescent lights and bulbs, does it through the action of electrons changing orbits and releasing photons (Bertolotti 51). A laser is a device that controls the way... although it is not a A+ probe it is an A+ essay. First irritative thing I picked out. My seco nd contention is with the lack of paragraphs! . Paragraphs = coherence. means wise it is good, although it is instead descriptive and doesnt have any plain argument rump it. I would be it an A- myself.

i regard your essay ahs a lot of great information however, i think the situation that their are no paragraphs makes it rather confusing and appear more like a page of facts thatn an essay. overall though, elegant dividing line! Very informative information, apparently, a lot of work went into this, I would empower it an A-, I agree with hoba, paragraphs are a must. Although I dont plan to use it, it is extremely informative, I agree. This is a A+ essay on Lazers. If it wont get you a A+ then nothing will.. Haha, If they had a rating higher than A+, then this would probally get it, lol. alough i beg to differ about the grade, this essay is nicly presented, not so much in strcture, further in information. really enjoyed reading this piece. The first thing I noticed about this essay was the lack of paragraphs. It makes it so heavy(p) to read, Reptromiki! This probably wasnt how it was originally presented though - computers are funny things when it comes to formatting. Otherwise, a good informative read - although 98% may be a little farfetched... I dont know many institutions/teachers that would select a mark so high. If you want to get a full essay, order it on our website: OrderCustomPaper.com
