    Why Can't Free-Particle Wave Functions Be Normalized Over Their Entire Range?

    this problem exist also about a particle in a square potential barrier!? what is the justification here? another question: we assume that wave function is zero at infinity while we couldn't observe such a thing in the cases of free particle and particle in a square potential barrier?

    Can’t specify the exact energy of system in a distinc timet

    ok but what is the Heisenberg uncertainty perinciple? you have seen at any modern physics books that Heisenberg uncertainty principle is 1.uncertainty between E and t & 2. uncertainty between x and p and according to uncertainty between E and t, you can say that: the lowest state of...

    Can’t specify the exact energy of system in a distinc timet

    According to uncertainty principle we can’t specify the exact energy of system in a distinc time On the other hand we say that for example: at t=0 system is in basic state of energy and according to time revolution we can specify it’s energy at the next time. There are contradiction!

    Why Can't Free-Particle Wave Functions Be Normalized Over Their Entire Range?

    why it is not possible to normalize the free-particle wawe functions over the whole range of motion of the particles?
