Electromagnetic Radiation Emission

Wolfram|Alpha includes a large database on the spectral lines for elements and isotopes. Find the visible spectrum of different substances. Obtain the transition probabilities and initial and final atomic states for different lines.
Emission

Compute the emission lines and their properties for all of the elements.

Use the Rydberg formula to compute spectral lines:

Rydberg formula ni=2, nf=5
