Question

de-Broglie equation describes the relation of wavelength associated with the motion of a particle and its:

• A. Energy
• B. Size
• C. Charge
• D. Momentum

Answer 1

The correct option is D Momentum

According to de-Broglie equation, the wavelength of a matter wave associated with a particle is inversely proportional to the magnitude of the particle's linear momentum.
$\lambda =\frac{h}{p}=\frac{h}{mv}$
where $\lambda$ is wavelength and $p$ is momentum associated with the particle.
