A) 16/3R
B) 2R/16
C) 3R/16
D) 4R/16
Correct Answer: C
Solution :
Wave number\[\left( \frac{1}{\lambda } \right)=R\left[ \frac{1}{n_{1}^{2}}-\frac{1}{n_{2}^{2}} \right]\] \[=R\left[ \frac{1}{{{(2)}^{2}}}-\frac{1}{{{(4)}^{2}}} \right]\] \[=R\left[ \frac{4-1}{16} \right]=\frac{3R}{16}\]You need to login to perform this action.
