- A
- B
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
Given: E1 is the energy for the transition from n=2→n=1 and E2 is the energy for the transition from n=3→n=2. Now the excitation energy is given as, ∆E=-13.6 1n12-1n22 ev For the first case, E1α 112-122=34 For the second case,…
