About this document
Group Velocity in Quantum Mechanics by khaledga65 is a document available to read on EtoBox.
This document discusses quantum mechanics and wave-particle duality. It begins by introducing the concept of De Broglie wavelengths and how particles can behave as waves. Later, it discusses the group velocity of a wave packet, how a particle is accompanied by a group of waves rather than a single wave. It derives an expression for the group velocity of a wave packet showing that it is equal to the derivative of the angular frequency with respect to the wave number and can differ from the phase velocity.
