Calcualte the limiting wavelengths of Balmer Series. If wave length of first line of Balmer series is 656 nm.

Explanation

To calculate the limiting wavelength of the Balmer series, we can use the Rydberg formula for hydrogen:

### Step 1: Understand the Rydberg Formula
The Rydberg formula is given by:
\[ \frac{1}{\lambda} = R \left( \frac{1}{n_1^2} - \frac{1}{n_2^2} \right) \]
where:
