How is the uncertainty principle mathematically expressed in terms of position (∆x) and momentum (∆px or ∆vx)?
Options
- A∆x = ∆px
- B∆x + ∆px = 1
- C∆x × ∆px = h/4π
- 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.
