Which of the following figures represents the variation of particle momentum and the associated de-Broglie wavelength?

1. (a)
2. (b)
3. (c)
4. (d)

Correct answer: (b)

Solution

The de-Broglie wavelength (λ) is inversely proportional to the momentum (p) of a particle, as given by λ = h/p. This implies a hyperbolic relationship, which is represented by option (b).
