Cycle of Photon - Essay ExampleA photon exudes particle-wave duality, hence has two characteristics of both a particle and a wave. It is of negligible visual sense and does not have electric charge. It has double states of polarization and can be described by three arguments. These arguments are wave vector components, wavelength and direction in which it is propagated. A photon moves with the speed of light in empty space and its might is affected by momentum and vector. A photon is among some of the rarest particles that are identical to their antiparticles, in this case, antiphoton. Photon is a generalised term used to explain the electromagnetic spectrum in the range of infrared emission (IR) radiation to visible light. Transition in the nucleus A photon is one particle that is able to transition in the nucleus of an atom. Though motion is peculiar(a) in the nucleus, a photon is able to change from one position to another. It is at the nucleus that the muscularity of an ato m is found. However, it is essential to note here that the form of the photon is not changed even though its speed is very high owing to the high take of energy in the nucleus. It moves along with angular momentum that is not mutually beneficial on its frequency. The component measured along its direction of motion, herein referred to as helicity, and must(prenominal) be an integer of the planks constant, denoted as h. Circular polarization states of the photon are derived from the two helicities described above, either positive or negative of planks constant. Motion of a photon gives rise to energy being produced and hence law of conservation of momentum must come into play. Conservation of momentum with reference to a photon is also referred to as transitional invariance and requires that more than two photons are created having null momentum. A bad sized photon has effects on the nucleus of an atom. Though said to be massless, its effects cannot be overlooked. A photon could alter Coulombs law and there would be pointless degrees of freedom for electromagnetic fields. Energy levels An atom has a varied emergence of energy levels also referred to as energy states. In each of these energy levels, electrons fluctuate with vibrations and thus produce energy. The number of electrons in each energy level increases as the distance from the nucleus increases. The greater the distance, the higher the energy emitted. A photon is emitted when an electron happens to move from a higher energy level to a lower energy level. The wavelength of the photon is the same as the distance between the two energy levels. This photon emitted has energy and this directly proportional to frequency and Planks constant but inversely proportional to its wavelength. The energy emitted by a photon is not dependent much on its mass since its mass is almost negligible though it is known that all matter has mass and occupies space. However, it is imperative to note that photons exhibit the same behaviour regardless of the energy level they are emitted by the transiting electrons. They travel at the same velocity even if moving from high energy level to lower energy level and the velocity can vary in over ten orders of magnitude from the lowest energies of radio waves to the powerful waves of gamma radiation. Photons are usually depicted as packets that carry energy with them though the energy in the packets is discrete. If the photons are travelling as a beam, intensity of such a beam depends on the number of photons per second. Light is also described as
