If the wavelength of the first member of Lyman series of hydrogen is λ . The wavelength of the second member will be
Options
- A27 32 λ
- B32 27 λ
- C27 5 λ
- D5 27 λ
Correct answer
A. 27 32 λ
Step-by-step solution
For Lyman series: For first member, 1 λ = 13 . 6 Z 2 h c 1 1 2 - 1 2 2 ….. (i) For second member, 1 λ ' = 13 . 6 Z 2 h c 1 1 2 - 1 3 2 ….. (ii) On dividing (i) and (ii), we get λ ' = 27 32 λ
