Quantum vs. Classical Mechanics :: essays research papers

perfect and Quantum mechanism are the two main field of chemical mechanism in physics. immaculate mechanics came a few hundred historic period before Quantum mechanics. Subsequently it is less accurate and less reliable therefore the more recent mechanic field of Quantum mechanics. Despite being outdated, Classical mechanics can still be used for many usual problems with bigger and slower travel objects. However, when dealing with extremely fast moving or small sub blood cellic particles a Classical approach depart non produce sufficiently accurate results as was the case round the nineteenth century.Difficulties with the Classical mechanics speculation came right around the 19th century. First was the Ultraviolet Catastrophe. Experimental data when testing blackbody beam of timid was found to be inconsistent with Classical mechanics. The data showed that as the wavelength of the ingress radiation approaches zero, the amount of energy being radiated also approaches zer o, whereas Classical mechanics says the emitted energy is infinite. The second difficulty with the theory was its inability to correctly show the photoelectric effect. The photoelectric effect says that photons from a surface are released when light hits it. Classical mechanics says that electrons will be emitted from a metal by light waves with any frequency as big as the forte of the light is strong enough, and even if it is weak over a long enough period of time electrons will eventually be emitted. The theory was proved incorrect after experiments showed that light under certain frequencies did not produce the photoelectric effect on the metal, which meant that the emitting of electrons is related not to vehemence but the waves frequency.A new string of mechanics, Quantum mechanics, was created in order to fragmentise the incompatibilities of Classical Mechanics. A main difference between the two fields of mechanics is the make up of the atom. In Quantum mechanics electrons in an atom are outside of the core group in particularized orbitals around the nucleus that they can jump from one to another only when a particular proposition energy level is reached, and can never be in-between the specific orbitals. Also Quantum mechanics says that a photon is released only when an electron jumps from a higher(prenominal) energy level to a lower energy level, or a higher energy orbital to a lower energy orbital. Classical mechanics, contradicting this, says that an atom is constantly emitting radiation.Quantum mechanics describes light as both a wave and a particle, depending on the situation.
