Wave-particle
duality and Uncertainty Principle
The concepts like
uncertainty principle and wave particle duality of
particles can stand only if the particles are constantly
in motion. But the question is where particles in the
nature are moving to demonstrate these phenomena? Of
course we can make particle in motion by artificial
methods like the experiments conducted by
Davisson-Germer or G.P. Thomson. In these experiments,
the electron beams are created by applying potential
difference between the anode and cathode in the
experimental setup. But today we know that, in an atom
there are two types of forces acting on its electrons.
They are attraction from the nucleus and repulsion
between electrons (in hydrogen atom attraction from the
nucleus only). But these forces cannot make the
electrons in an atom in motion.
