  • $\Delta x \times \Delta p \ge \frac{h}{{4\pi }}$
  • C
    $\lambda = \frac{h}{p}$
  • D
    $\Delta x \times \Delta p = \frac{h}{{6\pi }}$

Answer

Correct option: B.
$\Delta x \times \Delta p \ge \frac{h}{{4\pi }}$
b
(b) According to uncertainty principle, the product of uncertainties of the position and momentum, is $\Delta x \times \Delta p \ge h/4\pi $.
