Derive expression for the de-Broglie wavelength of an electron moving under a potential difference of V volt. Name an experiment which verified the wave nature of electrons.

Explanation

To derive the expression for the de-Broglie wavelength of an electron moving under a potential difference of V volts, we will follow these steps:

### Step 1: Understand the Work-Energy Principle
When an electron is accelerated through a potential difference \( V \), it gains kinetic energy equal to the work done on it by the electric field. The work done \( W \) on the electron can be expressed as:
\[ W = eV \]
where \( e \) is the charge of the electron.
