The Kinetic Energy of Electron during the Photoelectric Effect Calculator will calculate the:

- Kinetic energy of an electron extracted from metal during the photoelectric effect

**Calculation Parameters:** Medium of propagation is assumed as vacuum

The speed of electron (v) is m/s [metre per second] |

Speed of electron (v) calculation |
---|

v = √2 ∙ (h ∙ f - Φ)/mv = √ 2 ∙ ( ∙ - )/v = √ 2 ∙ /v = √ /v = √ v = |

Kinetic Photoelectric Effect Calculator Input Values |

Frequency of incident photon (f) Hz |

Work function of metal (Φ) J |

Planck's constant (h) J · s |

Mass of electron (m) kg |

v = √*2 ∙ (h ∙ f - Φ)**/**m*

This formula derives from Einstein's Equation of photoelectric effect

h ∙ f = Φ + *m ∙ v*^{2}*/**2*
