Anαparticle, a proton and an electron have the same kinetic energy. Which one of the following is correct in case of their de-Broglie wavelength:

Options:

Answer:
B
Solution:

As we know, de-Broglie wavelength is given by,

λ=hp

and p=2mK

Therefore,

λ=h2mK

As kinetic energy is the same for all particles,

λ1m

mα>mp>me

λe>λp>λα
