[lambda_(e)lambda_(e)" and "lambda_(a)" are the de Broglie wavelengths "],[" of electron,proton and "alpha" particle.If all are "],[" accelerated by same potential,then "]

lambda_(e),lambda_(p) and lambda_(alpha) are the de-Broglie wavelength of electron, proton and alpha particle. If all the accelerated by same potential, then

The de Broglie wavelength lambda of a particle

If lambda_(1) and lambda_(2) denote the de-Broglie wavelength of two particles with same masses but charges in the ratio of 1:2 after they are accelerated from rest through the same potential difference, then
