MCQ
In Heisenberg's uncertainty equation $\Delta x \times \Delta p \ge \frac{h}{{4\pi }}$; $\Delta p$ stands for
  • A
    Uncertainty in energy
  • B
    Uncertainty in velocity
  • Uncertainty in momentum
  • D
    Uncertainty in mass

Answer

Correct option: C.
Uncertainty in momentum
c
Heisenberg's uncertainty principle states that it is impossible to determine both the position and the momentum of a an electron inside an atom simultaneously.

Mathematically, it is derived that the product of uncertainties in position and momentum is greater than or equal to a constant $\frac{h}{4 \pi}$ The equation for that is:

$\Delta x . \Delta p \geq \frac{ h }{4 \pi}$ where,

$\Delta x=$ Uncertainty in position

$\Delta p =$ Uncertainty in momentum

$h =$ Planck's constant
