Schrodingers equation Flashcards
Idea behind schrodingers:
Particle behave likes wave is expanded on to the point it is distributed in space like a wave
Trajectory of particles:
Imprecise and instead we have a wavefunction
Wavefunction, Ψ
mathematical description of quantum system that varies with position.
Ψ restrictions
Must be continues, always finite, differentiable and single valued.
Time independent Schrodingers in 1 dimension.
-((ℏ^2)/2m) * d^2Ψ/dx^2 + V(x)Ψ = EΨ
What does Ψ tell us?
Fuck all but ΨΨ* is the probability density
Probability density integral:
∫ΨΨ*dx = 1, for one dimension
hbar :ℏ =
h/2pi
Hamiltonian operator, H =
LHS of schrodingers without Ψ
Hamiltonian equation
HΨ =EΨ
Schrodingers derivation
Ek +Ep = E
Ep = V(x)
Ek = p^2/2m, (p=mv)
p operator = ℏ/i *d.dx
Sub in and multiply by Ψ
