Quantum Physics For Beginners

What is certain is that electrons have intrinsic angular momentum

scientists have discovered that a photon of light can be split into two oppositely charged particle.

rotational energy.

In H=L2/2I where L is the angular momentum, I is the inertial moment of rotation.

KE=p2/2mwhere p is the momentum of a particle and mis its mass.

The potential energy of the particle is:

PE = ½ kx2 = ½ mω2x2

Classical physics provide that the quotient of the constant and the mass equate to the square of the angular frequency, thus

d2x/dt2+ ω2x = 0

In classical physics, harmonic oscillation is described by the Hooke’s law:

F = -kx

Harmonic oscillation could usually occur in the bonds of the atoms in a molecule

Energy (E) is greater than final V

In this state, the particle is not bound and is free to travel to both positive and negative infinities

Schrödinger equation:

-h2/2m ∇2 ψ (r) + V(r) ψ(r) =E ψ(r)

The square well

Initial V is less than the total energy, which is less than the final V (V
