What would be the de Broglie wavelength of an electron possessing 100 eV kinetic energy ?

Explanation

To find the de Broglie wavelength of an electron possessing 100 eV of kinetic energy, we can follow these steps:

### Step 1: Convert Kinetic Energy from eV to Joules
The kinetic energy (KE) is given as 100 eV. We need to convert this into joules using the conversion factor:
\[ 1 \text{ eV} = 1.6 \times 10^{-19} \text{ joules} \]
Thus,
