Problem: What is the wavelength of the line corresponding to n=5 in the Balmer series?

FREE Expert Solution

We can determine the wavelength, λ of the line corresponding to n=5 in the Balmer series using the Balmer Equation shown below:

Recall that for the Balmer series the final principal energy level nf is always = 2. 


1λ=R×1nf2-1ni2

λ  = wavelength, m 

R = 1.0974 x 107m-1 (Rydberg Constant)      **value can be found in textbooks or online 
ni = initial principal energy level
nf = final principal energy level = 2 for Balmer Series
