A) spin.
B) electric charge.
C) volume.
D) mass.

Question

Quizplus · Accepted Answer

The de Broglie wavelength ($\lambda$) of a particle is given by the equation $\lambda = \frac{h}{mv}$, where $h$ is Planck's constant, $m$ is the mass of the particle, and $v$ is its velocity. This equation shows that the wavelength is inversely proportional to both the mass (D) and the speed of the particle, but not to its spin, electric charge, or volume.
