Dtermine the accelerating potential necessary to given an electron a de Broglie wavelength of `1 7Å`, which is the size of the interatomic spacing of atoms in a crystal

Explanation

To determine the accelerating potential necessary to give an electron a de Broglie wavelength of \( 17 \, \text{Å} \), we can use the formula:

\[ V = \frac{h^2}{2 m_0 e \lambda^2} \]

where:
- \( V \) is the accelerating potential,
