Write the expression for the de Broglie ...

Write the expression for the de Broglie wavelength associated with a charged particle having charge q and mass , when it is accelerated by a potential V.

Text Solution

Verified by Experts

Kinetic energy acquired, `E = qV`
Momentum, `p = sqrt(2mE) = sqrt(2mqV)`
So, de Broglie wavelength, `lamda = (h)/(p) = (h)/(sqrt(2mqV))`
