STATEMENT : It is impossible to know simultaneously and with exactness both the position and momentum of a microparticle.

Expression :

APPLICATIONS : 1. To find the expression for Bohr's Orbit and Energy.2. To find the position of Particle in a Box.3. It confirms the non-existance of electroninside nucleus.

Born's Interpretation : The square of the magnitude of the wave function |Ψ|^2evaluated in a particularregion represents the probability of finding the particle in that region.

Normalization Condition :

A potential well is a potential energyfunction V(x) that has a minimum.,
