Sentence examples for an electron volt from inspiring English sources
Under these conditions, the temperature of the sample will be of the order of an electron volt (eV), which is higher than the melting and boiling points.
Spatial resolutions of less than 10 micrometers (μm) and photon energies of less than an electron volt make synchrotron IR spectromicroscopy noninvasive and useful for following the course of biogeochemical processes on complex heterogeneous surfaces of earth and environmental materials.
This can be a highly efficient method and has the experimental advantage of producing ions with a small energy spread characteristic of the filament temperature, typically a few tenths of an electron volt, as compared with beam energies of thousands of electron volts.
An electron volt is the amount of energy an electron would gain passing from the negative to the positive side of a one-volt battery.
(An electron volt is the amount of energy acquired by a single electron falling through a potential difference of one volt).
The electrons fed into it were first sped up using a midsized standard accelerator, so when they arrived at the glass accelerator they were already travelling at 99.86% of the speed of light, or 60m electron-volts (an electron-volt being the energy gained by an electron moving across an electrical potential of one volt).
The "quanta" of energy (ie, photons) carried by radio waves in, say, the UHF band used by television, Wi-Fi, Bluetooth, cordless phones, mobile phones, microwave ovens, garage remotes and many other household devices have energy levels of a few millionths of an electron-volt.
(An electron-volt is the energy with which a one-volt battery can accelerate an electron).
(By comparison, a proton is about a billion electron volts, and an electron is about half a million).
Typical energies of electrons within an atom range from a few electron volts to a few thousand electron volts.
