`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

Find the ratio of de Broglie wavelength of a proton and as alpha -particle which have been accelerated through same potential difference.

Find the ratio of de Broglie wavelength of a proton and as alpha -particle which have been accelerated through same potential difference.

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

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
