Mean Electron Velocity Solution

Follow our step by step solution on how to calculate Mean Electron Velocity?

FIRST Step Consider the formula

v e = \sqrt{\frac{2 \cdot IP}{[Mass-e]}}

Next Step Substitute values of Variables

∴

v e = \sqrt{\frac{2 \cdot 13.6eV}{[Mass-e]}}

Next Step Substitute values of Constants

∴

v e = \sqrt{\frac{2 \cdot 13.6eV}{9.1E-31kg}}

Next Step Convert Units

∴

v e = \sqrt{\frac{2 \cdot 2.2E-18J}{9.1E-31kg}}

Next Step Prepare to Evaluate

∴

v e = \sqrt{\frac{2 \cdot 2.2E-18}{9.1E-31}}

Next Step Evaluate

∴

v e = 2187234.0025294m/s

LAST Step Rounding Answer

∴

v e = 2.2E+6m/s

How to Evaluate Mean Electron Velocity?

Mean Electron Velocity evaluator uses Mean Electron Velocity = sqrt((2*Ionization Potential Barrier Suppression)/[Mass-e]) to evaluate the Mean Electron Velocity, The Mean Electron Velocity formula is defined as the speed of electron in a zero-range potential field which produces a barrier. The greater the ratio between the laser half-period and the tunneling time the greater the probability of an electron escaping to the continuum. Mean Electron Velocity is denoted by v_e symbol.

How to evaluate Mean Electron Velocity using this online evaluator? To use this online evaluator for Mean Electron Velocity, enter Ionization Potential Barrier Suppression (IP) and hit the calculate button.
