The wavelength of series limit for lyman series for `He^(o+)` would be

Options

A. `911.7 Å`
B. `227.9 Å`
C. `1215.1 Å`
D. `363.8 Å`

Explanation

To find the wavelength of the series limit for the Lyman series of the ion \( \text{He}^{+} \), we can use the Rydberg formula for hydrogen-like atoms. Here’s the step-by-step solution:

### Step 1: Write the Rydberg Formula
The Rydberg formula for the wavelengths of spectral lines in hydrogen-like atoms is given by:

\[ \frac{1}{\lambda} = RZ^2 \left( \frac{1}{n_1^2} - \frac{1}{n_2^2} \right) \]
