A hydrogen-like atom has electron energy levels given by E n = -18.00 eV 1/n2 with n =1, 2 and 3 (only).
a) Is the emission spectra of the atom line spectra or continuous? Why?
b) If it is line spectra, calculate the wavelengths of the emitted light photons.
c) Draw the electron transitions that produce the various photons.
