A) \[6.75\times {{10}^{12}}\,Hz\]
B) \[6.75\times {{10}^{14}}\,Hz\]
C) \[6.75\times {{10}^{13}}\,Hz\]
D) None of these
Correct Answer: C
Solution :
By using \[\nu =RC\,\left[ \frac{1}{n_{1}^{2}}-\frac{1}{n_{2}^{2}} \right]\] \[\Rightarrow \nu ={{10}^{7}}\times (3\times {{10}^{8}})\,\left[ \frac{1}{{{4}^{2}}}-\frac{1}{{{5}^{2}}} \right]\]= 6.75 ´ 1013 Hz
