Photon

actually seeing. Light is made up of both waves, and particles. These particles are called Photons, and all light is made up of these. Photons have no mass, thus allowing them to travel at the speed of light and its energy is always positive. A light wave is made up of these photons, meaning that are the composition of light itself. With this in mind, photons can hit each other, and do so very frequently. When photons bump into other atoms, much of their energy can get the electrons within those…

results in the brilliant display of light. “As the charged particles interact with charged atmospheric gases in Earth's ionosphere, the electrons in the gases move to higher energy states. As the excited electrons return to their ground state, light photons are emitted” (46 Lerner & Lerner). This entire process occurs hundreds of kilometres above earth, with the final result of luminescence appearing most often around 80-100 km, but with some appearing at levels of 500-800 km above earth. The…

greatly influences the LIGO interferometer is the output power of the laser. Sensitivity depends on the arm length and the resolution depends on the laser power. This is because as the power of the laser increases, more photons are generated. When higher number of photons merge at the beam splitter, sharper interference pattern is generated. According to theoretical calculations, a full sensitivity for LIGO can be achieved if the laser operates at 750kW. But the laser used in the LIGO can…

Albert Einstein's influence on astronomy. Albert had a big influence on Astronomy. He started to study mathematics, he was lured toward calculus around 1891. Albert originally wanted to be a electrical engineer. But he failed to do pass an examination which would have allowed him to study for a diploma at the Eidgenössische Technische Hochschule in Zurich. He made a plan of graduating as a teacher in mathematics and physics. He got his PHD in 1905. He also created the theory of relativity. A…

physicist Edmund Becquerel proposed that few materials have the ability to produce electricity when exposed to sunlight. But Albert Einstein explained the photoelectric effect and the nature of light in 1905. Photoelectric effect state that when photons or sunlight strikes to a metal surface flow of electrons will take place. Later photoelectric effect became the basic principle for the technology of photovoltaic power generation. The first PV module was manufactured by Bell laboratories in 1954…

conclusion of the experiment, the researcher will show what the optimal glow stick temperature will be for the longest amount of time a glow stick lights up (Light). In 1905, Albert Einstein proposed that light consists of quanta called photons also scientists measured photons in verified…

direction of the flow of electrons. In a semiconductor P-N junction, these electrons and holes are allowed to combine to emit a photon of light with energy equal to the difference of energies of the electron and hole. This emitted photon has a characteristic wavelength and frequency associated with this energy. Semiconductor P-N junctions can be engineered to emit photons of desired wavelengths and energies. However, the ability to engineer…

The way that a solution absorbs light is due to the photoelectric effect. The way the photoelectric effect works is that when light comes in contact with the sample, the photons of light will react with its electrons. As the light travels through the solution, "a photon of light may interact with an electron ... [where] the photon of light transfers all of its energy to the electron" (Papagapiou, 2016). Due to this process, creations such as solar panels and solar powered satellites are able to…

refered to as a molecule or atom which absorbs electromagnetic energy and in turn, emits light.In quantum mechanics, it is where excitation to a higher energy state occurs, which then returns to a lower energy state, together with the emission of a photon. According to Seitz (2006) found in the Credo referencing database, “Photoluminescence excitation spectra are determined by measuring emission intensity at a fixed wavelength while varying the wavelength of the incident light used to produce…

The subject of quantum physics appeared far-fetched to physicists of the late 18th and early 19th century. Now, scientists hold a better understanding of atoms and their properties because of this branch of physics. Many scientists helped create the utterly confusing and frightening field, but three in particular made improvements to it that directed modern scientists to where they stand today. People do not grant enough credit to Max Planck, Albert Einstein, and Louis-Victor Broglie, the…
