Question

According to the wave-particle duality of matter by de-Broglie, which of the following graph plot presents most appropriate relationship between wavelength of electron () and momentum of electron (p)?

• A.
• B.
• C.
• D.

Answer 1

Answer: (A)

Answer 2

By de-Broglie relation:

$\lambda = \frac{h}{p} \quad \text{(where $h$ is Planck’s constant)}$

This represents an inverse relationship between $\lambda$ and $p$, resulting in a rectangular hyperbola.
