Question

According to de Broglie, Which of the following statements is true about the wavelength of a moving particle?

• A. It is never large enough to measure.
• B. It is proportional to the speed of the particle.
• C. It is inversely proportional to the momentum of the particle.
• D. It is equal to Planck's constant
• E. It has no effect on the behavior of electrons.

Answer 1

The correct option is C It is inversely proportional to the momentum of the particle.

de Broglie wavelength associated with the particle $\lambda =\frac{h}{p}$

$⟹$ $\lambda \propto \frac{1}{p}$ where $h$ is the Planck's constant

Thus de Broglie wavelength is inversely proportional to the momentum of the particle
