Given below are two statements: Statement I: The value \( 109,677 \text{ cm}^{-1} \) is called the Rydberg constant for hydrogen. Statement II: The first five series of lines in the hydrogen spectrum known as Lyman, Balmer, Paschen, Bracket and Pfund correspond to \( n_1 = 1, 2, 3, 4, 5 \) respectively. In the light of the above statements, choose the most appropriate answer from the options given below:

  1. Both Statement I and Statement II are correct.
  2. Both Statement I and Statement II are incorrect.
  3. Statement I is correct but Statement II is incorrect.
  4. Statement I is incorrect but Statement II is correct.

Correct answer · Option 1

Both Statement I and Statement II are correct.

Explanation

Both statements correctly describe the Rydberg constant and the lower principal quantum numbers for the spectral series.
