Electrons are unique from the other particles in multiple ways. They exist outside of the nucleus, are significantly smaller in mass and exhibit both wave-like and particle-like characteristics. An electron is also anelementary particle, which means that it is not made up of smaller components....
Electron volt is defined as the energy acquired by an electron when it is accelerated through a potential difference of 1 volt. The value of electron volt (eV) is given as, 1 eV = (1.602 × 10-19 coulomb) × (1 volt) 1 eV = 1.602 × 10-19 joule ...
The measuring unit joule {eq}\left( {\rm{J}} \right) {/eq} and electron-volts {eq}\left( {{\rm{eV}}} \right) {/eq} are used to measure the quantity of energy as per requirement. Where, 1 electron volt is equivalent to {eq}1.6 \times {10...
The maximum loss of energy occurs when there is a head-on collision, and the photon is scattered back in the direction from where it arrived. Answer and Explanation: Compton scattering of a photon from an electron re...
To calculate wattage, you simply multiply voltage (pressure/speed) by amperage (volume), expressed asV x A = W. The faster each electron moves through the circuit, and the greater the volume that the circuit can hold, the higher the wattage. Wattage is measured in units called watts and ...
What is the difference between electric current and electron flow? Why are they in different directions? There is still a lot of confusion on this issue. It comes from when Benjamin Franklin first discovered electricity he thought it was positive charges that was moving along the wire. So the...
In other words, the bandgap is the energy required for an electron to transition from the valence band to the conduction band. Si has a bandgap of 1.12eV, SiC a bandgap of 3.26eV, and GaN a bandgap of 3.5eV. The unit for bandgap is eV (electron volt), which is defined as ‘the ...

In 2014, physicists thought they'd detected a 3.5 kiloelectron volt signal (keV) coming from deep within the Milky Way. This signal was believed to be consistent with what would arise from decaying sterile neutrino dark matter. In 2020, equipped with new data from the XMM-Newton space X-...
“Maybe magnetic fields are stronger than we thought, but that disagrees with other observations that show they’re not strong enough to produce significant curvature at these ten-to-the-twentieth electron volt energies,” said Belz. “It’s a real mystery.” ...
