A) IV
B) III
C) II
D) I
Correct Answer: B
Solution :
| \[E=Rhc\left[ \frac{1}{{{n}_{1}}^{2}}-\frac{1}{{{n}_{2}}^{2}} \right]\] |
| E will be maximum for the transition for which\[\left[ \frac{1}{{{n}_{1}}^{2}}-\frac{1}{{{n}_{2}}^{2}} \right]\]. is maximum. Here \[{{n}_{2}}\] is the higher energy level. |
| Clearly, \[\left[ \frac{1}{{{n}_{1}}^{2}}-\frac{1}{{{n}_{2}}^{2}} \right]\]is maximum for the third transition, i.e. \[2\to 1\]. I transition represents the absorption of energy. |
