MCQ
The de Broglie wavelength ' $\lambda$ ' of a particle
  • A
    is proportional to mass
  • B
    is proportional to impulse
  • is inversely proportional to impulse
  • D
    does not depend on impulse

Answer

Correct option: C.
is inversely proportional to impulse
(c) : de-Broglie wavelength of a particle is given by
$
\lambda=\frac{h}{p}
$
Here, impulse $=$ Change in momentum.
