The ware function
of
the particle is normalized. why?

Normalization of ψ(x,t): : is the probability density for finding the particle at point x, at time t. Because the particle must be found somewhere between x=-∞ and x=+∞ the wave. function must obey the normalization condition. Without this, the statistical interpretation would be meaningless.
