### Question 1.57

How do you find the wavelength of the next line in the series?
I keep looking up YouTube videos, but they all use different equations and they skip the explanation. Can someone please go over how to find the next line in details?
-THANK YOU :)

### Re: Question 1.57

You would use the following equation: $\Delta E = E_{f} - E_{i}$ (where $E =- \frac{hR}{n^2}$). It would also help to know what defines a Balmer series from others like Lyman or Paschen. The lowest energy of a Balmer series is n=2. Thus, you can presume what the next wavelength would be based on the trend of increasing n-value (E is also related to wavelength, so see if you can use this relationship and the above equation to find the answer).
