Question
The qualitative order of Debroglie wavelength for electron, proton and a particle is λe > λP > λα if
Options
A.If kinetic energy is same for all particles
B.If the accelerating potential difference ′V′ is same for all the particles (from rest)
C.If velocities are same for all particles
D.None of the above
Solution
λ = 
.
When v, KE and V are same, as m increasing, λ decreases. λe > λp > λα (if v, KE and V are same).
.When v, KE and V are same, as m increasing, λ decreases. λe > λp > λα (if v, KE and V are same).
