What is the de-Broglie wavelength associated with an electron moving with an electron, accelerated through a potential difference of 100 volt?

Explanation

Here, V=100volt
De-Broglie wavelength,
`lambda=12.27/(sqrtV) Å=12.27/(sqrt100)=1.227Å`
In this case the wavelegth associated with an electron is of the order of wavelength of X-ray.
