Question

calculate de broglie wavelength of an electron and a proton
having same kinetic energy of 100 eV

Neelam Yadav · Accepted Answer

Î» = h/âˆš2mE
where E = kinetic energy
m =mass of the particle
h= Plank's constant = 6 63 x 10-34
E = 100 eV =100 x 1 6 x 10-19 J
m =9 1 x 10-31 kg in case of electron while it is 1
67 x 10-27 kg in case of protons After putting all these
values you will get the wavelength for electrons and protons
