de Broglie Wavelength

Share with:


Alpha particle and a proton are accelerated from rest by the same potential. Find the ratio of their de- broglie wavelength


(Asked by Amritha)

 Answer:

Charge of alpha particle = 2e

Mass of alpha particle = 4 u

Charge of proton = e

mass of proton = u

The energy acquired by proton when accelerated through a pd of V,

E=eV

The momentum acquired by proton=

The de Broglie wavelength is given by 

Therefore, de Broglie wavelength of Proton,

Similarly,
