Question

Which of the following figure represents the variation of particle momentum (p) and associated de Broglie wavelength ($\lambda$)?

• A.
• B.
• C.
• D.

Answer 1

Answer: (D)

Answer 2

: de Broglie wavelength

$\lambda = \frac{h}{p}$

Or $\lambda \propto \frac{1}{p}$

Hence curve (4) is the correct option
