What are the speed and de broglie wavelength of an electron that has been accelerated by a potent5ial difference of `500 V`?

Explanation

To find the speed and de Broglie wavelength of an electron that has been accelerated by a potential difference of 500 V, we can follow these steps:

### Step 1: Calculate the Kinetic Energy of the Electron
The kinetic energy (KE) gained by an electron when it is accelerated through a potential difference (V) is given by the formula:
\[ KE = eV \]
where:
- \( e \) is the charge of the electron (\( 1.6 \times 10^{-19} \) coulombs)
- \( V \) is the potential difference (500 V)
