According to the Rydberg formula, the wavelengths of the first two spectral line in the Lyman series of the hydrogen spectrum, are

Options

A. `912 Å` & `3684 Å`
B. `684 Å` & `811 Å`
C. `1218 Å` & `1028 Å`
D. `915.4 Å` & `974.3 Å`

Explanation

To find the wavelengths of the first two spectral lines in the Lyman series of the hydrogen spectrum using the Rydberg formula, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Rydberg Formula**:
The Rydberg formula for the wavelengths of spectral lines in hydrogen is given by:
\[
\frac{1}{\lambda} = R \left( \frac{1}{n_f^2} - \frac{1}{n_i^2} \right)
