As a particle travels faster, its de Broglie wavelength
A) remains constant.
B) increases.
C) decreases.
D) could increase or decrease; it depends on other factors.

Question

Quizplus · Accepted Answer

The de Broglie wavelength of a particle is inversely proportional to its momentum. As a particle's speed increases, its momentum increases, leading to a decrease in its de Broglie wavelength.
