If the total energy of an electron in a hydrogen-like element in an excited state is -3.4 eV then the de-Broglie wavelength is equal to:
- \(6.6 \times 10^{-10} \mathrm{~m}\)
- \(3 \times 10^{-10} \mathrm{~m}\)
- \(5 \times 10^{-9} \mathrm{~m}\)
- \(9.3 \times 10^{-12} \mathrm{~m}\)
Answer
(D) 9.3 10^ -12 ~m
