The wavelength of the first spectral line of the Lyman series of hydrogen spectrum is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
1λ=R1n12−1n22⋅Z2 where, R= Rydbergs constant (Also written is RH) Z= atomic number Since the question is asking for 1st line of Lyman series therefore n1=1 n2=2 Since the electron is de-exited from 1st exited sate i.e.n=2 to ground sate i.e.n=1 for first line of…
