What principle states you cannot simultaneously know a particle's position and momentum?
Correct! The Heisenberg Uncertainty Principle states that the more precisely the position of a particle is determined, the less precisely its momentum can be known, and vice versa.
📘 Quantum Physics Formula Sheet
E = hf
Where:
- E = Energy of the photon
- h = Planck's constant (6.626 × 10⁻³⁴ J·s)
- f = frequency of the photon
Δx·Δp ≥ ħ/2
Where:
- Δx = uncertainty in position
- Δp = uncertainty in momentum
- ħ = reduced Planck constant (h/2π)
Ĥψ = Eψ
Where:
- Ĥ = Hamiltonian operator
- ψ = wave function of the system
- E = energy eigenvalue
λ = h/p
Where:
- λ = wavelength
- h = Planck's constant
- p = momentum of the particle
