Given that

Magnitude of accelerating potential of an electron V = 100 volts

Wavelength associated with an electron = ?

Step 1: Plug in the known values in the de Broglie wavelength

Broglie wavelength of the electron

\lambda = \frac{h}{p} = \frac{h}{\sqrt{2meV}}

or

\lambda = \frac{1.227}{\sqrt{V}}

Where,  V - magnitude of accelerating potential in volts

\lambda = \frac{1.227}{\sqrt{100}}

\lambda = 0.123 nm

In this case, the de Broglie wavelength correlated with the electron is of

X-ray wavelength order
