Question

Which of the following expressions gives the de-Broglie relationship?

• A. $p=\frac{h}{mv}$
• B. $\lambda =\frac{h}{mv}$
• C. $\lambda =\frac{h}{mp}$
• D. $\lambda \,m=\frac{v}{p}$

Answer 1

Answer: (B)

$\lambda =\frac{h}{mv}$

Answer 2

The de-Broglie relation is,
$\lambda=\frac{h}{m v}$
Where, $\lambda=$ de-Broglie wavelength
$h=$ Planck's constant
$m=$ mass of particle and $v=$ velocity of particle
