Question

An electron makes a transition from orbit n = 2 to orbit n = 1, in Bohr's model of hydrogen atom. Consider change in magnitudes of its kinetic energy (K) and potential energy (U).

Draw the energy level diagram for hydrogen atom. Mark the transitions corresponding to the series lying in the ultraviolet region, visible region and infrared region.

The diagram shows four energy level of an electron in Bohr model of hydrogen atom. Identify the transition in which the emitted photon will have the highest energy.

The ground state energy of hydrogen atom is –13·6 eV in Bohr model. An electron makes a transition from an energy level of –1·51 eV to that of –3·4 eV. Calculate the wavelength of the spectral line emitted.
