- B \(91.2 \mathrm{~nm}\)
- C \(182 \mathrm{~nm}\)
- D \(89.2 \mathrm{~nm}\)
Answer & Solution
Correct Answer
(B) \(91.2 \mathrm{~nm}\)
Step-by-step Solution
Detailed explanation
Sequence of series in hydrogen spectrum are Lyman series \((n=1)\), Balmer series \((n=2)\), Paschen series \((n=3)\), Bracket series \((n=4)\) and Pfund series \((n=5)\). For Lyman series, \(n_1=1\) For shortest wavelength in Lyman series i.e., the energy difference in two…
