What is the difference between field emission and photoelectric emission?
* emisssion of electron from the surface of the metal when light of suitable frequency falls-photoelectric emission. * emision of electron from the metal by quantum tunnling of electron.
How do positron emission and electron capture change an atom?
After positron emission or electron capture the atomic number is decreased with one.
What are 4 methods of electron emission?
1- Secondary Emission 2- Thermionic Emission 3- Field Emission 4- Photo-Electric Emission Badbanky
Thermionic Emission of electron is due to?
Heat
What does FESEM mean in electron microscopy?
Field Emission Scanning Electron Microscopy
The emission of a positron also results in the creation of?
If you are talking about beta+ decay, then the emission of a positron is accompanied with the emission of an electron neutrino.
What has the author I Garnett Barber written?
I. Garnett Barber has written: 'Secondary electron emission from copper surfaces' -- subject(s): Secondary electron emission
What determines an elements emission spectrum?
The electron energy levels.
Why are no two emission spectra for different elements ever the same?
Because emission spectrum are the result of the electron configuration of the element and no two elements have exactly the same electron configuration.
In a beta particle emission what does the neutron split into?
a proton and an electron
In beta decay what is emitted?
Beta- decay involves changing a neutron into a proton, with the emission of a W- boson, said boson then decaying into a electron and an electron antineutrino. Beta+ decay involves changing a proton into a neutron, with the contribution of energy, and then the emission of a positron and an electron neutrino.
What are definitions of electronics and electric?
Electronics is electrons emission electric is electron flow.
