Question

The kinetic energy of an electron which is accelerated through a potential of $100$ volts is:-

Answer 1

According to Broglie's equation,

Wavelength associated with electron through potential difference V is given as ,

$\lambda =\frac{12.27}{\sqrt{v}}=\frac{12.27}{\sqrt{100}}=\frac{12.27}{10}=1.227A$

The wavelength corresponds to X-rays.
