which of the following figures represent the variation of

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

Dual Nature of Matter and Radiation mcq option image

Answer : Dual Nature of Matter and Radiation mcq option image

Solution :
The de-Broglie wavelength is given by
$$\lambda = \frac{h}{P} \Rightarrow P\lambda = h$$
This equation is in the form of $$yx = c,$$ which is the equation of a rectangular hyperbola. Hence, the graph given in option (B) is the correct one.
