Question

which of the following particle moving with same velocity has maximum de Broglie wavelength?
a.electron. b.proton
c neutron. d.alpha-particle​

Answer 1

• Now, since all the particles are moving with same velocity, the particle with least mass will have maximum de-Broglie wavelength. Out of the given four particles (proton, α− particles, i.e. He nucleus and β− particles, i.e. electrons) β− particles has the lowest mass and therefore it has maximum wavelength.
