Question

The increasing order of wavelength for H e + ion, neutron (n) and electron e − particles, moving with the same velocity is, λ H e + λ e λ n, λ H e + = λ n = λ e, λ H e + λ n λ e, λ e λ n λ H e +

∵ λ = h m ⋅ v (As per de-Broglie relation) ∴ λ ∝ 1 m (h and v are constant) Also, ∵ m H e + > m n > m e ∴ λ H e + λ n λ e
