Q1

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

a

\({\lambda }_{d}>{\lambda }_{p}>{\lambda }_{e}\)

b

\({\lambda }_{e}>{\lambda }_{p}>{\lambda }_{d}\)

c

\({\lambda }_{\mathrm{p}}>{\lambda }_{\mathrm{e}}>{\lambda }_{\mathrm{d}}\)

d

\({\lambda }_{e}={\lambda }_{\mathrm{p}}={\lambda }_{\mathrm{d}}\)
