An electron is accelerated through a potential difference of 100 volts. What is the de-Broglie wavelength associated with it ? To which part of the electromagnetic does this value of wavelength correspond ?

Explanation

To solve the problem, we will follow these steps:

### Step 1: Understand the de-Broglie Wavelength Formula
The de-Broglie wavelength (\( \lambda \)) of a particle can be calculated using the formula:
\[ \lambda = \frac{h}{p} \]
where \( h \) is Planck's constant and \( p \) is the momentum of the particle.
