Question

Show on a graph the variation of the de Broglie wavelength $\lambda$ associated with an electron, with the square root of accelerating potential ($V$)

Answer 1

As we know that,

De-Broglie wavelength $\left(\lambda \right)=\frac{1.22}{\sqrt{V}}$

So, $\lambda \sqrt{V}=const$

Hence, we get a rectangular hyperbola.
