An electron in the ground state of the hydrogen atom has the orbital radius of $\displaystyle 5.3 \times 10^{-11} \mathrm{~m}$ while that for the electron in third excited state is $\displaystyle 8.48 \times 10^{-10} \mathrm{~m}$. The ratio of the de Broglie wavelengths of electron in the ground state to that in the excited state is
