Question

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.

A hydrogen atom makes a transition from n = 5 to n = 1 orbit. The wavelength of photon emitted is λ. The wavelength of photon emitted when it makes a transition from n = 5 to n = 2 orbit is

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.
