De Broglie Packet Calculator Input Values |

Mass of particle (m) kg [kilogram] |

Initial speed of particle (v_{0}) m/s [metre per second] |

Final speed of particle (v) m/s [metre per second] |

Planck's constant (h) J · s [Joule per second] |

Archimedes' Constant (π) |

Section 1: Units and Measurements

∆k = *2π ∙ m · (v - v*_{0})*/**h*

This formula derives from

∆k = *2π ∙ ∆p**/**h*

where Δp = m · Δv = m · (v - v_{0}) is the change in particle's momentum.
