The graph showing the correct variation of linear momentum (p) of a charge particle with its de-Broglie wavelength (λ) is _____________.

विकल्प

MCQ

उत्तर

The relation between de-Broglie wavelength and the momentum is:

`lambda = h/p`

⇒ `p = h/lambda`

By the above relation, we can conclude that the graph between the momentum and the de-Broglie wavelength is a rectangular hyperbola.

Hence, the correct answer is
