Lyman Series v Balmer series

Postby Angel Gomez 1K » Fri Oct 13, 2017 4:44 pm

Can someone explain the difference between the Lyman and Blamer series to me? I couldn't really determine the difference when looking at the graphs Lavelle showed us during lecture. Fundamental difference would be great, and further detail would be much appreciated!

The main difference between the Lyman and Balmer series is the energy level in which electrons come to rest. For the Lyman series n=1, while for the Balmer series n=2.
Another important characteristic to note is that the Lyman series is found within the ultraviolet spectrum, while the Balmer series is within the visible spectrum.

Just to add on, since the Lyman series have a shorter wavelength, they indicate that a greater amount of energy is being absorbed (because E=hv, v=c/wavelength). If you recall the model from lecture, this means the electrons are making a bigger "jump", such as from the first level to the second (later levels are closer together, which correspond more to the Balmer series).
