Debroglie wavelength for an electron and proton moving at same speed are $\rm{L_{e}}$ and $\rm{L_{p}}$ respectively and frequencies are $\rm{F_{e}}$ and $\rm{F_{p}}$ respectively. Then which of the following is correct.

Question

Accepted Answer

$\rm{F_{e} < F_{p}\,\, , \,\,L_{e}>L_{p}}$

Answer

$\rm{F_{p} < F_{e}\,\, , \,\,L_{e}<L_{p}}$

Answer

$\rm{F_{e} = F_{p}\,\, , \,\,L_{e}<L_{p}}$

Answer

$\rm{F_{e} > F_{p}\,\, , \,\,L_{e}>L_{p}}$
