If the potential difference used to accelerate electrons is tripled, by what factor does de Broglie wavelength of electrons beam change ?

Text Solution

Verified by Experts

de Broglie wavelength of electrons accelerated through a potential difference of V volts is
`lambda = ( h )/( sqrt( 2 mqV))`
When accelerating voltage V is tripled, the de Broglie wavelength becomes `(1)/( sqrt(3))` times.
