Probability Density Calculator

Calculate probability of finding a quantum particle in a region

System Type:

Box Length L (m):

Quantum Number n:

Position x1 (m):

Position x2 (m):

Particle in Box: |psi_n|^2 = (2/L)*sin^2(n*pi*x/L)

Hydrogen 1s: |psi|^2 = (1/(pi*a0^3))*exp(-2r/a0)

Radial Prob Density: P(r) = 4*pi*r^2*|psi|^2
