This formula uses 1 Constants, 4 Variables
Constants Used
[hP] - Planck constant Value Taken As 6.626070040E-34 Kilogram Meter² / Second
Variables Used
Energy of Particle in Box along x Direction - (Measured in Joule) - Energy of Particle in Box along x Direction is defined as the energy values that a particle can have residing in a level.
Energy Levels along x Direction - Energy Levels along x Direction are the quantised levels where the particle may be present.
Mass of Particle - (Measured in Kilogram) - Mass of Particle is defined as the energy of that system in a reference frame where it has zero momentum.
Length of Box along x Direction - (Measured in Meter) - Length of Box along x Direction gives us the dimension of the box in which the particle is kept.
STEP 1: Convert Input(s) to Base Unit
Energy Levels along x Direction: 2 --> No Conversion Required
Mass of Particle: 9E-31 Kilogram --> 9E-31 Kilogram No Conversion Required
Length of Box along x Direction: 1.01 Angstrom --> 1.01E-10 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Ex = ((nx)^2*([hP])^2)/(8*m*(lx)^2) --> ((2)^2*([hP])^2)/(8*9E-31*(1.01E-10)^2)
Evaluating ... ...
Ex = 2.39109478237349E-17
STEP 3: Convert Result to Output's Unit
2.39109478237349E-17 Joule -->149.24033298945 Electron-Volt (Check conversion here)
149.24033298945 149.2403 Electron-Volt <-- Energy of Particle in Box along x Direction

## What is the physical significance of particle in a box ?

Consider a particle of mass m
that is allowed to move only along the x-direction and its motion is confined to the region between hard and rigid walls located at x=0 and at x=L. Between the walls, the particle moves freely. This physical situation is called the infinite square well, described by a potential energy function.
