What is in electron volt physics?

Electron Volt (EV) is a very small unit of energy that is used in the field of physics, such as nuclear and particle physics, partly because of the fact that the standard unit of energy, joule, is too great to make clear significance in the research as a basic unit. The standard electron volt value is calculated as 1.602 x 10

-19 or a fraction of 0.00000000000000001602 Joule. The value is derived from the energy needed to move a single electron electrical potential of one volt or as an equivalent amount of energy that one photon light bears. One trillion electron volts (TEV), or 1 x 10

12 EV, is still so low energy value in the fact that it is considered equivalent to the amount of working energy spent when it moves, and the standard 100-watt bulb burns 2,200,000,000 times than an hour per hour.Advance scientific research, where in some calculations it may represent values ​​for temperature or electromagnetic radiation. This includes astronomy where it is used to categorize wavelengths of light. This is because electron volt is a basic measurement of kinetic energy that can be practically used for research at a molecular level. The value of 13.6 EV is equal to the energy needed to ionize hydrogen atom, which is the most common element that occurs in astronomical research. The value of 4.2 EV is needed to divide the salt molecule into sodium and chloride elements, making electrons of Volta a suitable term for many common chemical reactions.

Despite its expanded use in research, electron Volt is not considered a standard metric unit, as its value may change on the basis ofxperimental conditions and requirements. It can also be used to represent weight in the calculations of physics to balance the energy units in a special relativity equation E = MC ²

. UmoIt varies the calculation of the weight of subatomic particles, such as protons, where one proton corresponds to 938,000,000 EV divided by light speed into the other, which is expressed as a giga electron volts in short as 0.938 Gev/C

There is no direct conversion into electron volts from standard volts as a scale of electrical potential. While the two seems to be a derivative, it is a measurement of various things, with electron volts as a meant of kinetic energy based on joule and Volts as a scale of a potential difference between two conductive points. However, electron volts monitor the metric convention to increase the quantity, while the kilometer prefix represents 1,000 in Kev; mega representing one million or mev; Giga representing one billion in Gev; Attaches further.
