MCQ
de-Broglie equation is
  • A
    $\lambda=\frac{h v}{m}$
  • B
    $\lambda=\frac{m v}{h}$
  • C
    $\lambda= hmv$
  • ✓
    $\lambda=\frac{h}{m v}$
✓

Answer

Correct option: D.
$\lambda=\frac{h}{m v}$
(d) $\lambda=\frac{h}{m v}$
Explanation: Louis de-Broglie proposed that matter, like light, has a dual character.It exhibits wave as well as particle nature. The wavelength of the wave associated with a particle of mass m moving with velocity v is given by $\lambda=\frac{h}{m v}$
