Discover Physics with free Physics Revision Notes and Physics Calculator: De Broglie Packet. This image shows the properties and de broglie packet formula for the De Broglie Packet. The Width of De Broglie Packet Calculator will calculate the width of De Broglie packet when particle's mass and speed in two different instants are given

Width of wave packet (Δk) Formula and Calculation

∆k = 2π ∙ m · (v - v₀)/h

This formula derives from

∆k = 2π ∙ ∆p/h

where Δp = m · Δv = m · (v - v₀) is the change in particle's momentum.
