InterviewSolution

1.	The energy of an electron in the second and the third Bohr orbit of hydrogen atom is −5.42×10−12 erg and −2.41×10−12 erg respectively. Calculate the wavelength (cm) of the emitted radiation when an electron drops from the third to the second orbit.
Answer» The energy of an electron in the second and the third Bohr orbit of hydrogen atom is $- 5.42 \times 10^{- 12} e r g$ and $- 2.41 \times 10^{- 12} e r g$ respectively. Calculate the wavelength $(c m)$ of the emitted radiation when an electron drops from the third to the second orbit.
