MCQ
Minimum de-Broglie wavelength is associated with
  • A
    Electron
  • B
    Proton
  • C
    $C{O_2}$ molecule
  • $S{O_2}$ molecule

Answer

Correct option: D.
$S{O_2}$ molecule
d
(d) $\lambda = \frac{h}{{mv}}.$ For same velocity $\lambda \propto \frac{1}{m}$.

$S{O_2}$ molecule has least wavelength because their molecular mass is high.
