1.	The energy of an electron in the second and the third Bohr's orbits of a hydrogen atom is −5.42×10−12 erg and −2.41×10−12 erg respectively. Calculate the wavelength of the emitted radiation when the electron drops from the third to the second orbit.
Answer» The energy of an electron in the second and the third Bohr's orbits of a hydrogen atom is $- 5.42 \times 10^{- 12} erg$ and $- 2.41 \times 10^{- 12} erg$ respectively. Calculate the wavelength of the emitted radiation when the electron drops from the third to the second orbit.
