Question 1.11

Postby Emily 1E » Tue Apr 17, 2018 8:16 pm

In the spectrum of atomic hydrogen, several lines are generally classified together as belonging to a series (for example, Balmer series, Lyman series, Paschen series), as shown in Figs. 1.10 and 2.1. What is common to the lines within a series that makes grouping them together logical?

The answers say that each series has a different lower energy level, but what does the "lower energy level" mean in this context? Isn't the lower energy level n=1?

they start off in the same energy level so that is why grouping them is logical

The lower energy level in this context is referring to the level that each series starts at. UV light corresponds to n=1, visible light corresponds to n=2, and infrared light corresponds to n=3. When you do problems with the different series, when they say "lower energy level", you must assess what type of light it is and then decided what your lowest n value can be.
