A) \[R\]
B) \[\frac{3R}{4}\]
C) \[\frac{5R}{36}\]
D) \[\frac{8R}{9}\]
Correct Answer: C
Solution :
According to Bohr's principal wave number is \[\bar{v}=R\left( \frac{1}{n_{1}^{2}}-\frac{1}{n_{2}^{2}} \right)\] From Blamers? first line \[{{n}_{1}}=2,\] \[{{n}_{2}}=3\] \[\bar{v}=R\left( \frac{1}{{{2}^{2}}}-\frac{1}{{{3}^{2}}} \right)\] \[=\frac{5R}{36}\]You need to login to perform this action.
