What is the de-Broglie wavelength (in

{nm}

) of an electron in the ground state of hydrogen atom is ?

\text { [K.E. }=13.6 \,{eV} ; 1 \,{eV}=1.602 \times 10^{-19} {~J} \text { ] }

View answer and explanation

Correct option: A

0.33

Option A (0.33) is correct because it is the de-Broglie wavelength calculated using the kinetic energy of the electron.
