Question
Which is the acceptable normalized wave function of particle in 1D box
Solution
The acceptable normalized wave function of a particle in a 1D box (also known as a particle in a box or an infinite potential well) is given by the solution to the Schrödinger equation for this system.
The wave function, often denoted as Ψ(x), is:
Ψ(x) = sqrt(2/a) * sin(nπx/a)
where:
- a is the width of the well
- n is a positive integer (n = 1, 2, 3, ...) representing the energy level or quantum number
- x is the position of the particle in the well
This wave function is normalized, meaning that the total probability of finding the particle in the well is 1. This is a requirement for all valid wave functions in quantum mechanics.
The sine function ensures that the wave function goes to zero at the edges of the well (x = 0 and x = a), which is a boundary condition for the particle in a box problem. The square root factor ensures that the wave function is normalized.
