MCQ
Which one is not the correct relation in the following
  • A
    $h = \frac{E}{v}$
  • B
    $E = m{c^2}$
  • $\Delta x \times \Delta p = \frac{h}{{4\pi }}$
  • D
    $\lambda = \frac{h}{{mv}}$

Answer

Correct option: C.
$\Delta x \times \Delta p = \frac{h}{{4\pi }}$
c
(c) $\Delta x \times \Delta p = \frac{h}{{4\pi }}$ is not the correct relation. But correct Heisenberg’s uncertainty equation is $\Delta x \times \Delta p \ge \frac{h}{{4\pi }}$.
