A hydrogen atom in its ground state is excited to the $n=5$ level. It then makes a transition directly to the $n=2$ level before returning to the ground state. (a) What are the wavelengths of the emitted photons? (b) Would any of the emitted light be in the visible region?
(a) What is the smallest amount of energy in electron volts that must be given to a hydrogen atom initially in its ground level so that it can emit the $H_{\alpha}$ line in the Balmer series? (b) How many different possibilities of spectral-line emissions are there for this atom when the electron starts in the $n=3$ level and eventually ends up in the ground level? Calculate the wavelength of the emitted photon in each case.

For an electron in a hydrogen atom, calculate the energy of the photon emitted when an electron falls in energy from the $n=5$ level to the $n=2$ state. What are the frequency and wavelength of this electromagnetic radiation?
