How is the uncertainty principle mathematically expressed in terms of position (∆x) and momentum (∆px or ∆vx)?

Options

  1. A∆x = ∆px
  2. B∆x + ∆px = 1
  3. C∆x × ∆px = h/4π
  4. D∆x × ∆vx = h/4π

Correct answer

C. ∆x × ∆px = h/4π

Step-by-step solution

The mathematical expression of the uncertainty principle as ∆x × ∆px = h/4π, where ∆x is the uncertainty in position, and ∆px (or ∆vx) is the uncertainty in momentum (or velocity) of the particle.
