- B.It links the particle's momentum to its wave properties.
- C.It determines the charge of the particle.
- D.It measures the energy of the particle.
Model answer
What a good answer should say
- It links the particle's momentum to its wave properties.
Explanation
Why this works
The de Broglie wavelength provides evidence that particles have wave characteristics by relating their momentum to a wavelength. This shows that as particles move, they can exhibit wave-like behavior, which is a fundamental aspect of quantum mechanics.
The implication is that understanding this relationship is crucial for explaining phenomena like electron diffraction. Therefore, the de Broglie wavelength is essential for describing wave-particle duality.
