A) \[1.214\times {{10}^{-7}}m\]
B) \[2.816\times {{10}^{-7}}m\]
C) \[6.500\times {{10}^{-7}}m\]
D) \[8.500\times {{10}^{-7}}m\]
Correct Answer: A
Solution :
\[\frac{1}{\lambda }={{R}_{H}}{{Z}^{2}}\left( \frac{1}{n_{1}^{2}}-\frac{1}{n_{2}^{2}} \right)\] \[Z=1\] \[{{n}_{1}}=1\] \[{{n}_{2}}=2\] \[\lambda =1.214\times {{10}^{-7}}m\]You need to login to perform this action.
