How many spectral lines are emitted by atomic hydrogen excited to the n-th energy level?

How many spectrual lines are emitted by atomic Hydrogen, when an electron jumps from 5th energy level to ground state ?

An electron in an excited hydrogen atom acquired an energy of 12.1 eV. To what energy level did it jump? How many spectral lines may be emitted in the course of the transition to lower energy level? Calculate the corresponding wavelengths.

In an experiment on the photo-electric effect Singly ionized helium is excited electronically to different energy levels. The light emitted by ionised helium is incident on photo-electric plate in a photocell. When helium is excited to fourth energy level, then the observed stopping potential of the photocell is found to be five times the stopping potential measured when the photoelectrons are produced by using light emitted by hydrogen atom, excited to the third energy level. Determine the work function of the material of the photo-electric plate.
