Let \(\lambda_{{e}}, \lambda_{{p}}\) and \(\lambda_{{d}}\) be the wavelengths associated with an electron, a proton and a deuteron, all moving with the same speed. Then the correct relation between them is
- \(\lambda_{d} \gt \lambda_{p} \gt \lambda_{e}\)
- \(\lambda_{{e}} \gt \lambda_{{p}} \gt \lambda_{{d}}\)
- \(\lambda_{p} \gt \lambda_{e} \gt \lambda_{d}\)
- \(\lambda_{e}=\lambda_{p}=\lambda_{d}\)
Answer
(B) _ e _ p _ d
