A spectral line in the Balmer series of hydrogen spectrum corresponds to wavelength 6561Å. Find the energy levels involved in the transition responsible for the origin of this line `(R=109679cm^(-1))`.

Explanation

To solve the problem of finding the energy levels involved in the transition responsible for the spectral line in the Balmer series of hydrogen spectrum corresponding to a wavelength of 6561 Å, we can follow these steps:

### Step-by-Step Solution:

1. **Convert Wavelength to Wave Number**:
The wave number (\( \bar{\nu} \)) is given by the formula:
\[
\bar{\nu} = \frac{1}{\lambda}
