In Quantum Mechanics, a particle is best described by the concept of a Wave packet. Now, what is a Wave packet? That is what we will discuss in this video.

In QM, a wave packet is a fundamental concept used to describe the behavior of particles at the quantum level. It represents a localized and often temporary concentration of a particle's probability amplitude in a specific region of space.
Imagine a particle, such as an electron, whose behavior is described by a wave function. This wave function is a mathematical expression that characterizes the probability distribution of finding the particle at various positions in space. A wave packet is essentially a wave function that is strongly peaked in a limited spatial region. Wave packets are crucial for understanding the behavior of particles at the quantum level.
